Wcmatch

- **FIX**: Small bug in `[:alpha:]` range.

- **NEW**: `WcMatch`'s `on_init` hook now only accepts `kwargs` and not `args`.
- **NEW**: Cosmetic change of referring to the first `__init__` parameter as `root_dir` instead of `base`. This is to make it more clear when we are talking about the overall root directory that all paths are relative to vs the base path of a file which is relative to the root directory and the actual file name.
- **NEW**: Internal attribute of `WcMatch` changed from `base` to `_root_dir`. This attribute is not really meant to be referenced by users and as been marked as private.
- **NEW**: Drop requirement for `backrefs` and update documentation to note that POSIX properties never actually enabled the use of Unicode properties. While the documentation stated this and it was probably intended, it was never actually enabled. Currently, Wildcard match has chosen to keep with the ASCII definition for now as it has been since the feature was introduced. This may change in the future if there is demand for it.
- **NEW**: Add `[:word:]` POSIX character class.

- **NEW**: Drop Python 3.5 support.
- **NEW**: Formally support Python 3.9 support.
- **FIX**: Small fix for regular expression output to ensure `NODIR` pattern looks at both `/` and `\\` on Windows.

- **NEW**: Translate functions will now use capturing groups for `EXTGLOB`/`EXTMATCH` groups in the returned regular expression patterns.

- **FIX**: Ensure that when using `REALPATH` that all symlinks are evaluated.
- **FIX**: Fix issue where an extended pattern pattern can't follow right behind an inverse extended pattern.
- **FIX**: Fix issues related to nested inverse glob patterns.

- **NEW**: Recognize extended UNC paths.
- **NEW**: Allow escaping any character in Windows drives for better compatibility with `SPLIT` and `BRACE` which
requires a user to escape `{`, `}` and `|` to avoid expanding a pattern.
- **NEW**: `raw_escape` now accepts the `raw_chars` parameter so that translation of Python character back references can be disabled.
- **NEW**: Search functions that use `scandir` will not return `.` and `..` for wildcard patterns that require iterating over a directory to match the files against a pattern. This matches Python's glob and is most likely what most users expect. Pattern matching logic is unaffected.
- **NEW**: Add `SCANDOTDIR` flag to enable previous behavior of injecting `.` and `..` in `scandir` results.
`SCANDOTDIR` has no affect on match functions such as `globmatch` which don't use directory scanning.
- **NEW**: Flag `NODOTDIR` has been added to disable patterns such as `.*` from matching `.` and `..`. When enabled, matching logic is changed to require a literal pattern of `.` and `..` to match the special directories `.` and `..`. This is more Zsh like.
- **FIX**: Negative extended glob patterns (`!(...)`) incorrectly allowed for hidden files to be returned when one of the subpatterns started with `.`, even when `DOTMATCH`/`DOTGLOB` was not enabled.
- **FIX**: When `NOUNIQUE` is enabled and `pathlib` is being used, you could still get non-unique results across
patterns expanded with `BRACE` or `SPLIT` (or even by simply providing a list of patterns). Ensure that unique results are only returned when `NOUNIQUE` is not enabled.
- **FIX**: Fix corner cases with `escape` and `raw_escape` with back slashes.
- **FIX**: Ensure that `globmatch` does not match `test//` with pattern `test/*`.
- **FIX**: `pathlib.match` should not evaluate symlinks that are on the left hand side of what was matched.
