fix: catch OverflowError and TypeError in filesize._to_str()

[koteshyelamati]

Problem

_to_str() in fs/filesize.py only catches ValueError when converting the size argument to int, but two other exceptions can occur:

• int(float('inf')) raises OverflowError, not ValueError
• int(None) raises TypeError, not ValueError

This means callers passing float('inf') or None get an unexpected bare OverflowError/TypeError instead of the informative TypeError message the function is designed to produce.

>>> from fs.filesize import traditional
>>> traditional(float('inf'))
# OverflowError: cannot convert float infinity to integer
# (instead of: TypeError: filesize requires a numeric value, not inf)

Fix

Extend the except clause to also catch OverflowError and TypeError:

except (ValueError, TypeError, OverflowError):
    raise TypeError("filesize requires a numeric value, not {!r}".format(size))
