Christiaan Dirkx 94d73d4403 Refactor parse_prefix on Windows
Refactor `get_first_two_components` to `get_next_component`.

Fixes the following behaviour of `parse_prefix`:
 - series of separator bytes in a prefix are correctly parsed as a single separator
 - device namespace prefixes correctly recognize both `\\` and `/` as separators
