test/fix 24-bit and 32-bit encoding

[justinruggles]

Need to test 32-bit encoding.
Need to fix 24-bit encoding.
Will post test details later...

[justinruggles]

24-bit files are tagged as 32-bit, so they don't decode to match original.
CRC is not calculated correctly for 24-bit files.

[justinruggles]

Well, this seems more complicated than I thought. I applied what I thought was a fix to the 24-bit issue but now it gives noise when decoded. Still working on a solution.

[justinruggles]

ok, I'm pretty sure this is fixed now. We just need to do some extensive testing.

Oh I've not seen these comments before...
I think I correctly encoded with 24 bit yesterday so I think this is fixed, too.
I will add 24 bit files into my conformance test suite and report back then.

[thiloborgmann]

I successfully tested encoding using the 24b wave file included in the conformance files via our .als muxer. Ignoring the original wav header, the restored samples are identical.

p.s. valid reconstruction tested for compression-levels 1-3

[justinruggles]

Great. I'm pretty sure 32-bit is fine, but we need to test this as well.
