v0.4.0

SciMLOperators v0.4.0

Diff since v0.3.14

This is not a breaking change according to semver. There is no breaking change to the public APIs. However, there is an issue with Julia's precompilation model that makes it so that this release is incompatible with the new added fallbacks. Thus every package other than SciMLBase.jl should simply accept this new version.
