PST/SQRT + Benches (#35)

Browse Source 
* first version of the sqrt PST without the MIPP

* snarkpack integration

* snarkpack integration

* adding mipp as submodule directly

* snarkpack integration

* finalizing

* snarkpack integration

* update mipp with latestest optimisations and add preliminary
documentation

* improve codebase documentation

* remove unused imports and apply cargo fix changes

* passing v0.4

* adding gh action

* correct workflow item

* correct working dir and msrv

* remove unnecessary stuff

* wip

* wip

* remove circuit in fq as it's not needed now

* done for tonight

* wip

* wip

* sip

* prallelise commitment and groth16 verification

* finalise comments for mipp

* wip

* finalise comments

* wip

* compiling but test failing

* putting back non random blinds

* using absorb when we can

* absorbing scalar

* with bls12-381

* stuff

* trying to bring ark-blst to testudo

* correcting random implementation

* with square in place

* works with blst

* works with blst

* fix: don't require nightly Rust

With removing the `test` feature, it can also be built with a stable
Rust release and don't require a nightly Rust version.

* using ark-blst main branch

* started cleanup and added testudo benchmark

* add testudo snark and nizk in separate files

* rename functions that perform setups and add comments

* prototyping

* explain testudo-nizk

* add support for odd case in sqrt_pst

* add missing constraints and correct proof size for benchmarks

* add support for odd case in sqrt_pst

* fix typo in comment

* Documentation #31

* fix typo in comment

* Fix Cargo.toml and add benchmark for sqrt pst (#34)

* add benchmark for sqrt pst

* fix typo in comment

* add README

* comment from readme not executing
