RUSTSEC-2021-0061: `aes-ctr` has been merged into the `aes` crate

[github-actions]

aes-ctr has been merged into the aes crate

Details
Status	unmaintained
Package	aes-ctr
Version	0.3.0
URL	RustCrypto/block-ciphers#200
Date	2021-04-29

Please use the aes crate going forward. The new repository location is at:

<https://github.com/RustCrypto/block-ciphers/tree/master/aes>

The aes crate now has an optional ctr feature which autodetects SIMD
features on i686/x86-64 targets and uses them if available, or otherwise
falls back to the implementation in the ctr crate.

If you would prefer not to have this autodetection performed, use the aes
crate directly with the ctr crate.

See advisory page for additional details.
