flac: Refuses to decode certain big-frame files

[H2Swine]

Created .flac files that ffmpeg refuse to decode, and managed to construct such one inside subset:
​https://hydrogenaud.io/index.php/topic,125848
Using a noisy signal I could create a CDDA file that is also rejected, but then I had to specify non-subset block size.

Also, while I'm at it: Wouldn't it be an idea after all these years to allow 8-bit FLAC encoding? And fix the ​ffplay playback of block sizes < 128 (even if, whothef¤¤c uses ffplay ... - anyway, that bug also verified yesterday with 7.0)

How to reproduce:

Patches should be submitted to the ffmpeg-devel mailing list and not this bug tracker.

whothef¤¤c uses ffplay

Limitations in it are limitations in other software typically. Interesting.

It fixed here I imagine. ​https://github.com/librempeg/librempeg/commit/5425767bc66bf56f1f4d0cdcfbdcff9cfd4e72a2
