attached is a vanilla abstraction to read binary files like
[mrpeach/binfile].

it allows both [read <filename>( and [read <filename> <maxsize>(.

caveats:
- if the file-size is not a multiple of 2, the last byte is omitted!
- when using the <maxsize> feature, you get an ugly error-like warning
on the Pd-console.
- it's not super-efficient. especially it reads the entire (up to
<maxsize> bytes) file into memory twice. so it's probably not a good
idea to use this with large files.
it also outputs the entire file as a list of bytes (as opposed to
[mrpeach/binfile] which just gives you have to bang to get the next byte).
