Major release for KLayout 0.25 using Packages, split Tools and PDK

We are releasing v0.3.0, which is a major restructuring of the code and splits the Tools part from the EBeam-PDK, thus supporting for multiple PDKs.
This version supports installation using KLayout 0.25's new Packages feature.

Leaving behind v0.1.x

We are moving to v0.3.0, which is a major restructuring of the code and splits the Tools part from the EBeam-PDK, thus supporting for multiple PDKs.
