Allow, block regex parameter name inconsistency

[panabar]

Hi @asweigart,

Thank you for the python books and this module. While trying pyinputplus.inputStr() while reading the readme.md I noticed the following inconsistency.

The readme file states:

whitelistRegexes (Sequence, None): A sequence of regex str that will explicitly pass validation, even if they aren't numbers. Defaults to None
blacklistRegexes (Sequence, None): A sequence of regex str or (regex_str, response_str) tuples that, if matched, will explicitly fail validation. Defaults to None.

The parameters() function in init.py

def parameters():
    """
    Common parameters for all ``input*()`` functions in PyInputPlus:
...
    * ``allowlistRegexes`` (Sequence, None): A sequence of regex str that will explicitly pass validation.
    * ``blocklistRegexes`` (Sequence, None): A sequence of regex str or ``(regex_str, error_msg_str)`` tuples that, if matched, will explicitly fail validation.
...
    """

However, the named parameters in the actual functions are allowRegexes and blockRegexes.
