OPT: speeds up FileTree updating

See merge request fsl/fslpy!229

Replaces deepcopy with a smarter copy implementation, which only copies the instance attributes.

This is a speedup of about 20x (and yes, the deepcopy was getting annoyingly slow in some of my code).

Also minor bugfix - allow forward or backslash after \\wsl$ when
specifying FSLDIR as a WSL network share

The problem here is not that it can't find the folder but that FSLDIR
suggests a WSL installation but does not match the format required to
identify the distro folder.

This requires  WSL 2.0 but enables FSLDIR to be a genuine
WIndows path so that atlases and standard data can be loaded
transparently. It also means we no longer need FSLWSL environment
variable, just to be a bit careful with path mapping

This means that users who have FSL installed in Windows Subsystem
for Linux can call the wrappers directly from a Windows python
program (after setting the environment variable FSLWSL=1)

Previously only the long versions of options were correctly flagged
as booleans, but the -b and -B options do not have long alternatives
so they need to be supported too. And for familiarity to command line
users we should support other single-char switches too
