Fix types for MarkerStyle

QuLogic · QuLogic · commit 1e28c2ea1987 · 2023-05-31T02:17:45.000-04:00
It is not possible for `get_marker` to return another `MarkerStyle`; the
`__init__` only takes one to make a full copy of it. And `get_alt_path`
is only available for e.g., half-filled markers, but not all.
