[FEATURE]: expose support for brotli compression

[JamieMagee]

minizlib has had support for brotli compression since 1.3.0, which was updated here in 0973296.

tar(1) has support for brotli compression currently via the -I/--use-compress-program option. For example:

tar -I brotli -cf archive.tar.br archive

But I've also proposed adding a top-level --brotli flag: https://lists.gnu.org/archive/html/bug-tar/2023-06/msg00002.html

I like the idea.

In keeping with the pattern of mapping tar(1) options to node-tar options, I guess it'd be { I: 'brotli' } or { useCompressProgram: 'brotli' }? It's a bit weird to call it a "compress program" when it's all the same "program" though 🫤 Maybe those two could be aliases for compressAlgorithm or something?

tar(1) supports some algorithms (bzip2/xz/lzip/lzma/lzop/zstd) via -I/--use-compress-program that don't overlap with node-tar's support.

I think adding a brotli option or a compress option would be simpler. So you can provide options like:

const opts = {
  brotli: <true|brotli options> // same as gzip options
}

or

const opts = {
  compress: {
    algorithm: 'brotli', // or 'gzip'
    options: {
      level: 9
    }
  }
}

What do you think?
