This adds the usual crate metadata (URL, keywords, etc). Also sets the MSRV to 1.73 (needs to be at least 1.73 for div_ceil), and add a CI job to test the MSRV build. The job only builds ext4-view (doesn't run tests since we don't necessarily need test code to be restricted to the same MSRV, and doesn't build the xtask package since its deps could require a higher MSRV).
