v0.3.0

Feature

• Make it support dimensionality 2 and 1.

Enhancements

• Make a libyt stub that binds to Enzo and Gamer simulation datasets. Compare if using yt_libyt with libyt will generate the same output as the one by directly plotting based on the static dataset on a hard disk. Datasets are downloaded from yt data-hub, and it will be cached.

Fix

• GitHub Action drop supports for runner ubuntu-20.04.
• Face-centered data should consider index offset when reading data. (currently, Enzo which has index offset 1, doesn't use this feature. so this is first discovered.)
