s is the string to decode. Optional casefold is a flag specifying whether
a lowercase alphabet is acceptable as input. For security purposes, the
default is False.
RFC 3548 allows for optional mapping of the digit 0 (zero) to the letter O
(oh), and for optional mapping of the digit 1 (one) to either the letter I
(eye) or letter L (el). The optional argument map01 when not None,
specifies which letter the digit 1 should be mapped to (when map01 is not
None, the digit 0 is always mapped to the letter O). For security
purposes the default is None, so that 0 and 1 are not allowed in the
input.
The decoded string is returned. A TypeError is raised if s were
incorrectly padded or if there are non-alphabet characters present in the
string.
