Bump MSRV to 1.79

The associated type bounds feature, stabilized in 1.79 allows adding
an implied Send bound on all IntoFuture types used with MaybeFuture,
so every function doesn't have to be marked as Send.

This is going to be especially useful with wasm, because it allows the
Send bound to be turned on and off in one place.
