feat: rename crates from gejdr-crud to georm

This commit renames gejdr-crud to georm for an easier name to remember
in case I publish `georm` and `georm-macros`. This commit extracts the
`Georm` (formerly `Crud`) trait from `gejdr-core` to its dedicated
crate `georm` on which gejdr-core now depends.

Currently writing tests
