Kotlin Multiplatform port

Similar to #59 and #19, I decided to make a pure Kotlin port of this library.

Although on the server side, Kotlin has compat with Java libraries, I wanted to make it a Multiplatform lib because why not.

Currently there is no README, but when I finish it, I'm going to mention this repo in the README.

The port is here, under `kt-string-similarity`: https://github.com/solo-studios/kt-fuzzy
