Comment (by spookybathtub):

 Thanks for your work on this.  Since there is no way to identify Prores
 bit depth by reading a metadata flag, I suggest to always decode Prores
 444 as 12-bit by default, unless the user chooses 10-bit with a command-
 line flag to improve speed.  Prores 422 can remain as 10-bit.
 Keep in mind the alpha channel should be 16 bits.  Although I have
 personally never seen a Prores file with alpha.
