should use semantic versioning on releases

I hope [Semantic Versioning](https://semver.org/) is the de facto on versionin. Steps

1. On preparing releases if we don't break API's we increase `MINOR` version both in `build.gradle` and tag a repo using `vMAJOR.MINOR.PATCH` for `jitpack` to propagate new release
2. For android it may be trick cause `versionName is string` and `versionCode is long`. A simple library(or app) may use convection `MAJOR*1000+MINOR*100+PATCH*10` i.e `v0.5.1` versionCode become `510` and `v1.5.1` become `1510`
3. For bigger apps they can even mix `min SDK version` on deriving `versionCode`
