Perl implementation of SplatHash: integrate under src/perl or link externally?

[M-M-M-M]

Hi @junevm ,

I have published a Perl implementation of SplatHash:

• Repository: https://github.com/M-M-M-M/SplatHash-In-Perl
• First stable release: https://github.com/M-M-M-M/SplatHash-In-Perl/releases/tag/v1.0.0
• Reference commit used for the port: 038b4f7025ec044ed9f319371e0ec2ed863a6f45

The implementation provides:

• 16-byte encoding and 32x32 RGBA decoding
• image-file encoding through Imager
• a command-line interface
• deterministic bit-for-bit parity tests against Go-generated RGBA vectors
• Perl-versus-Go benchmarks using the upstream image assets
• an MIT licence with the upstream attribution preserved

Before preparing a pull request, I would like to ask which integration model you would prefer:

1. Copy the implementation into this repository under src/perl, following the existing Go, TypeScript, and Python layout.
2. Add a link in the implementations/install section to the external Perl repository and its releases.
3. Keep the Perl port fully independent and do not reference it here.

If you prefer src/perl, I can adapt the port to the repository contribution requirements, including tests that encode every upstream asset, a test:perl task in mise.toml, and the README implementation entry.

I currently maintain the Perl port in its own repository, so I would also appreciate your preference regarding long-term ownership and synchronization when the SplatHash algorithm changes.

Would you be interested in including or referencing this implementation, and which approach would you prefer?

Thanks.
