ICU_jll is not compatible with Julia < 1.6.

This package may need to drop support for Julia < 1.5.

Using Pkg, ICU_jll version can be obtained and this method seems to work.

Thank you for your PR!
I have tagged a new version of StrICU with this change (and updating the tests to use 1.6 & 1.10), as v1.2.0.
