Breaking changes has been released as patch version

[inoyakaigor]

In our company we have own UI kit that relies onto this package. After update react-unicons to 2.2.4 from 2.2.1 I can't build my app because of renaming an icon uil-calender.js to uil-calendar.js. I mean this change https://github.com/Iconscout/react-unicons/pull/122/files#diff-720cf2b5260a606a674d1b9e7338d354dc865da33b0e4884d57bcb681988024d
Of course I rolled back to working version but I think such change as renaming something should be releasing as major version in future.

Thank you!

UPD: I've just found there was a lot more renamings v2.0.2...v2.2.4
