React 18/React Admin 4.5 updates

[ababra]

Breaking changes:

• This PR significantly deviates from it's forked project, in that a reorganization of the folder structure was required to allow this to be added as a git source, instead of as an NPM package, i.e. yarn add <git_remote_url> - not sure if you want to actually merge this, created this PR for informational purposes mainly
• The main issue with getting this package to build under React Admin 4.5 appears to be a change in naming of lodash.omitBy vs lodash.omitby
• Also had to update the tsconfig.json with a number of options to get this to compile
