The final jar size of kotlin-faker library is ~20M . Looking at the jar contents, icu lib takes most of the size , with locales files and shadowed jackson being the next two.

icu was added in this commit: a556f24#diff-a6fced4b4e4a99784a2b92028b1adbc8c0ca28ff54e264b0e73727b3d4a460cf , but why is it relocated and included in the final jar? I think this can be changed and included as a regular dependency, which should reduce the jar size to 5M.

Further, using minimize function with the shadowJar might reduce the jar size even more.
