explicit imports

[JeffFessler]

Module MIRT is relying on implicit imports for 5 names. These could be explicitly
imported as follows:

using Interpolations: Interpolations, Gridded, Linear, extrapolate, interpolate

Additionally, module MIRT has stale explicit imports for these 6 unused names:

•  LinearMapAM is unused but it was imported from LinearMapsAA at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/nufft/nufft.jl:14:34
•  LinearMapAO is unused but it was imported from LinearMapsAA at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/nufft/dtft.jl:16:34
•  bfft! is unused but it was imported from FFTW at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/system/Asense.jl:8:42
•  fft! is unused but it was imported from FFTW at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/system/Asense.jl:8:36
•  nfft is unused but it was imported from NFFT at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/nufft/errors.jl:10:24
•  nfft_adjoint is unused but it was imported from NFFT at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/nufft/errors.jl:10:30

Additionally, module MIRT explicitly imports 4 names from non-owner modules:

•  bfft! has owner AbstractFFTs but it was imported from FFTW at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/system/Asense.jl:8:42
•  fft! has owner AbstractFFTs but it was imported from FFTW at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/system/Asense.jl:8:36
•  nfft has owner AbstractNFFTs but it was imported from NFFT at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/nufft/errors.jl:10:24
•  nfft_adjoint has owner AbstractNFFTs but it was imported from NFFT at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/nufft/errors.jl:10:30

Additionally, module MIRT explicitly imports 1 non-public name:

•  show_unquoted is not public in Base but it was imported from Base at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/io/shows.jl:8:13

Additionally, module MIRT accesses 4 non-public names:

•  EltypeUnknown is not public in Base but it was accessed via Base at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/algorithm/general/ls-mm.jl:211:44
•  InterpolationType is not public in Interpolations but it was accessed via
   Interpolations at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/utility/interp1.jl:28:25
•  SizeUnknown is not public in Base but it was accessed via Base at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/algorithm/general/ls-mm.jl:210:42
•  haar is not public in Wavelets.WT but it was accessed via Wavelets.WT at
   /Users/fessler/.julia/packages/MIRT/PbauD/src/regularize/Aodwt.jl:38:21

[JeffFessler]

After the update to v0.18.3 via #146, most of the above is addressed. The remaining issues are with other packages (including Base!) that have not yet declared public many of their public methods.

Module MIRT is not relying on any implicit imports.

However, module MIRT explicitly imports 2 non-public names:

•  InterpolationType is not public in Interpolations but it was
   imported from Interpolations at
   /Users/fessler/.julia/packages/MIRT/GvXsP/src/utility/interp1.jl:9:24
•  show_unquoted is not public in Base but it was imported from Base
   at /Users/fessler/.julia/packages/MIRT/GvXsP/src/io/shows.jl:8:13

Additionally, module MIRT accesses 3 non-public names:

•  EltypeUnknown is not public in Base but it was accessed via Base
   at
   /Users/fessler/.julia/packages/MIRT/GvXsP/src/algorithm/general/ls-mm.jl:211:44
•  SizeUnknown is not public in Base but it was accessed via Base at
   /Users/fessler/.julia/packages/MIRT/GvXsP/src/algorithm/general/ls-mm.jl:210:42
•  haar is not public in Wavelets.WT but it was accessed via
   Wavelets.WT at
   /Users/fessler/.julia/packages/MIRT/GvXsP/src/regularize/Aodwt.jl:38:21
