tpm2-protocol: open for patches

[Jarkko Sakkinen <jarkko@kernel.org>]

Hi

The last version that I do "as solo":

https://crates.io/crates/tpm2-protocol/0.10.10

I lifted up the version number in the main branch so that ABI breaks can
be done [1]. Consider all versions up 0.10.10 as the PoC era of this
project. I'm neither to motivated to pick up any stable fixes for 0.10.x.

Versions starting from 0.11 (once it is released) 0.11.x, bug fix
(no feature) branches can be done.

There's one feature in my test program (which I don't recommend to use
for any production, it's still heavily under construction) that I'm
willing to consider for relicensing and further to contribute e.g.,
to TPM-RS or perhaps as its own crate:

https://github.com/puavo-org/tpm2sh/blob/main/src/pretty_printer.rs

[lot's of unimplemented parts but it does not trip on them but instead
 marks them down to the log]

Keep in mind that the constraints in the following sections (taken from
lib.rs) are the existential limits for any possible patch (including
dev dependencies, do that type of stuff at your own personan sandbox
thank you).

## Constraints

* `alloc` is disallowed.
* Dependencies are disallowed.
* Developer dependencies (aka 'dev-dependencies`) are disallowed.
* Panics are disallowed.

## Design Goals

* The crate must compile with GNU make and rustc without any external
  dependencies.
