Removing or overriding font awesome dependancy

[andybroomfield]

This is a followup to #39 and #47.
The issue has come up as we are trying to replace font awesome use on our site with our own icon set.
As far as I can tell this is only a requirement of the submodule localgov_homepage_paragraphs in order to provide the paragraph localgov_ia_block.
Since this is a submodule, do we need the hard requirement to install fontawesome provided by composer.json, could we not move this to composer suggest? (We'd have to add a release note exaplaining that if you use this paragraph type, you need to install this manually to keep it.
Checking the dependancy chain, it's then required by localgov_subsites_paragraphs and then by localgov_subsites.

For the moment, we can disable loading the fontawesome library so it's not a super urgernt deal, but it is another module we are getting installed without really needing it.

So would we be able to remove the dependancy, and would that nessacitate a breaking change needing a major release?

Note the localgov_ia_block was for creating the icons as seen on the BHCC homepage, which is where I think they originated from, though I think only BHCC implemented using them, not sure how they got tied to Subsites.

I think removing the requirement would require people putting it in the their composer.json
Is this easiest done along with other things that's going to require a version bump... ie along with the D10 upgrade? #113
