Increase maximum_iterations parameter to 100

[tsmbland]

Description

The example models were previously using a range of values for the maximum_iterations parameter, ranging from 1 to 100. As explained in the issue (#372), this should be a high number, so I've changed all the models to use 100 and regenerated the results files.

I've also changed the default value from 3 to 100 (i.e. when not specified in the settings file)

I've based this PR off #349 as that one is already changing all the results files. There may be some text changes required in the notebooks (e.g. describing plots), but I'll address these sorts of things in #349 once this is merged

Fixes #372

Type of change

Please add a line in the relevant section of
CHANGELOG.md to

• Bug fix (non-breaking change which fixes an issue)
• Breaking change (whatever its nature)

Key checklist

• All tests pass: $ python -m pytest
• The documentation builds and looks OK: $ python -m sphinx -b html docs docs/build

Further checks

Looks sensible to me. It's interesting to see how the output files change, adding more assets installed in the future years. I hope those changes still make sense!
