Added cutting layout style strictMax support and improved strategy for maximum widths

[BenJamesBen]

This PR contains code changes discussed in freesewing/freesewing#3909 to improve the packing strategy for fabric cutting layout applications.

• Use a different strategy when there is a maximum width: fill the bin to the maximum width before increasing the height.
• Retain the original strategy when there isn't a maximum width: fill the bin in a way that forms a roughly square shape.

It also implements strictMax in a way that:

• Still packs items wider than the maximum width. It does this by placing the item at the left edge of the bin.
• Does not increase the width of the bin even if a wider-than-maximum item has been packed. (Narrower-than-maximum items are still packed inside the maximum width.)

(The previous developers seemed to intend that strictMax functionality, when implemented, would reject items wider than the maximum width. I've left these intentions intact in the comments and the test stub, even though their intentions may be no longer relevant to this fork of the project.)

I bumped the version number to 1.0.2 in package.json. I am not sure if that was appropriate or if the version should be changed to 1.1.0.
