Subject: [PATCH 2/2] chore: bump MSRV to 1.57

Motivation: to improve panic messages in const fns, which without this are a
horrible experience for users. As we make more `from_static` constructors
usable in a const context, this is worth the increase.

We're still able to build on Debian oldstable.
