MD5 checksum added by default on wavpack exports

[dg-no-9]

Resolves: WavPack export: include MD5 audio checksum (-m option)

The Flag 'CONFIG_MD5_CHECKSUM' set to the exporter API config. The exported wavpack files should have MD5 checksums by default after this fix.

I don't believe this is sufficient. The wavpack documentation states:

CONFIG_MD5_CHECKSUM: specify if you plan to store MD5 signature (the sum is
calculated by the application, NOT by the library)

Simply passing the argument as you did here just sets the flag which promises there will be an MD5 sum in the file (00A3 in my file), but it doesn't actually calculate and write the MD5 sum.

@LWinterberg Thanks for note. Yes, Wavpack API seem to require MD5 from the application itself. I see that wavpack/cli has its own md5 for their testing I suppose. Do we have any MD5 library, if not we probably need to add it to support this feature.

I see an md5 thing in some of the vendored libraries still in lib-src/, but probably not one which wants to be used here. Adding md5 to libraries/lib-crypto might be worthwhile.
