8d501cfcc6 add a check that the detached signature metadata matches signed data 
the unsigned metadata in the signature header is used to compute
the signature, which contains a copy of the key metadata. We forgot
to make sure these match, which means the signed copy was worthless.

Until now.

dc527a3619 Rust 1.56 results in a bigger loader. Presumably because "optimization". 
This causes the font maps to shift down. Allocate some "room to grow"
as Rust gets more "optimal".

e93929e04b loader: use vendered version of utralib 
By vendoring this package, we can avoid causing a rebuild unnecessarily.

This will be removed when Rust 1.55 is released and we can bring the
`loader` package back into the main workspace.

4c777976ac clear RAM on a cold boot 
since the RAM is battery backed and persistent, it's probably
a good idea just to zero-ize it before using it on a cold boot.
