Bump dependencies

[morehouse]

Update to the latest stable versions for all dependencies.

chacha20poly1305 v0.11 deprecates Nonce::from_slice, so we use nonce_bytes.into() instead.

Smoke tested by fuzzing LDK with the IR scenario for several hours.

I ran cargo upgrade --incompatible, and I see that some dependencies were not fully bumped. For eg: toml = "1.1" and cc = "1.4", Is there any reason for pinning them to their existing or lower versions?

The version in Cargo.toml specifies the minimum requirement in the current major release (or minor release if major is 0). I only updated dependencies in Cargo.toml that had to be updated to get the latest stable versions. toml and cc are still in the 1.x major release series, so there's no need to update them in Cargo.toml. I just ran cargo update and the latest versions were automatically bumped in Cargo.lock:

[[package]]
name = "toml"
version = "1.1.5+spec-1.1.0"

[[package]]
name = "cc"
version = "1.4.5"

I think this is the right approach to bumping dependencies unless there's a specific feature we need from a minor release -- then we would need to pin the latest version.
