dompdf version bump to include 3.0 when?

[jurchiks]

Describe the problem

Currently PHPWord only supports dompdf/dompdf ^2.0, but recently dompdf released v3: https://github.com/dompdf/dompdf/releases/tag/v3.0.0

Judging from the changelog and diff (dompdf/dompdf@v2.0.8...master), there don't seem to be any BC breaks, certainly no API breaks, aside from very few type additions to method signatures, which shouldn't break anything.

This would indicate that bumping the version requirement to dompdf/dompdf ^2.0 || ^3.0 shouldn't cause any problems.

Currently I cannot update my own dompdf version because it conflicts with the phpword requirement, which is, understandably, a pain in the ass.

Describe the expected behavior

Dompdf ^3.0 is supported.

Priority

• I want to crowdfund the feature (with @algora-io) and fund a community developer.
• I want to pay the feature and fund a maintainer for that. (Contact @Progi1984)
