Some docstrings are formatted poorly

[jhkennedy]

The bulleted lists in the asf_tools.water_map.make_water_map docstring render poorly, smooshing the bullets into the paragraph:

The bulleted lists affected:

• https://github.com/ASFHyP3/asf-tools/blob/develop/asf_tools/water_map.py#L173-L180
• https://github.com/ASFHyP3/asf-tools/blob/develop/asf_tools/water_map.py#L190-L193
• https://github.com/ASFHyP3/asf-tools/blob/develop/asf_tools/water_map.py#L198-L199

Similarly, true for asf_tools.flood_map.make_water_map, but this time they are being interpreted as italics markers:

• https://github.com/ASFHyP3/asf-tools/blob/develop/asf_tools/flood_map.py#L148-L155

There may be more...
