This change adds verbiage to the readme about MSRV policy and removes a declared MSRV from the profiling crate itself, due to it being dependent on what backend is enabled. CI is now updated to test 1.70.0/stable/beta for the profiling crate, and stable/beta for the demo.
It's likely profiling itself can build under significantly older versions of rust but 1.70.0 changed the way dependencies are resolved and runs faster in CI.
