base64 decode doesn't handle alternative alphabets

base64 allows for alternate 62nd and 63rd characters. The LDAP {SSHA} scheme allows for this, but cudaHashcat-plus 0.14 doesn't seem to like. I get either a crash or the offending character in the hash is converted to an 'A'. For example:

foobar hashes to:

{SSHA}cdE9?c1HqhqfM7stWIbexLPqadQQUuVy

% ./cudaHashcat-plus64.bin -m 111 -d 2 ../ck3 ../foobar.dict
