AutoSAS Widget Issues

[martintb]

Here are a few lingering issues that could be fixed with the AutoSAS widget:

• q range bounds should be detected from data if data is provided
• The parameter list should only have one checkbox called "bounded"
• All parameters should be included into the AutoSAS dictionary, fixed if unchecked, bounded if checked
• Dump model inputs into next cell rather than just in the widget object

Progress bar for fitting progress would be good. TDQM for total number of fits
