mpg123: bump to 1.31.3

upstream changes:

1.31.3
------

- build:
-- Fix --disable-8bit.
-- Fall back to generic decoder if no yasm for MSVC (bug 346).
-- Fix some pedantic compiler warnings, avoid breaking libtool wrappers.
- mpg123:
-- Fix verbose position printout for new resampling outside libmpg123 (where
   output rate differs from decoding rate).
- libsyn123:
-- Fix reconfiguration of resampler to avoid double free when reducing
   decimator stages to zero (bug 350). Thanks to Youngseok Choi for reporting
   this fuzzed issue.
