ENH: Relax trimeshpy version

Relax `trimeshpy` version so that more recent versions are allowed: the
changes in the classes used in `tractodata` are safe and do not affect
the behavior: they only drop checks for `VTK` <= 5 and 8, adopt keyword
arguments in some calls, use Python built-in types (e.g. `int` instead
of `np.int`), use `NiBabel`'s `affine` property on NIfTI images, and
drop `future` imports.
