Add support for new Sharp styles

[robmadole]

In PR #213 we added support for Sharp Solid. We now have Sharp Regular and Sharp Light.

Let's use #213 as a template and add the newer styles.

As part of this work, we should look at adding support for sharp-duotone styles as they come out.

@robmadole i have prepared a PR to migrate this addon to v2...
When we are getting that, we don't need anymore todo this changes in future when FA is adding new packages... the move to v2 addon is braking, but solves a lot of maintainence costs.
See #239
