v0.3

Features

• Add automatic reimport when file change. (Thanks to @tullrich )
• Add support for scriptable asset importer, will be activated after v2019.4. (Meanwhile right-click import workflow will be disabled)
• This will be the last version that current import workflow (right click->ASE->Import) will be used. We will fully embrace scriptable importer in later versions. This means future MetaSprite versions will not support unity versions under 2019.4.

Improvements

• Some UI usability improvement and better error hint.

Bugfixes

• Fixes a crash when trying to read out-of-boundary pixels (#9 )
