Image utilities update

[TimMonko]

• improve docstrings
• move around some methods to be more clear
• type some methods
• small ui updates for clarity
• change function of open next to select next
• update tests as needed, but no breaking changes
• use bioio when possible, and fallback to aicsimageio, for now
