Ensure Circom 1 tests pass with experimental Circom 2 support (#18)
* All tests pass under circom-2 feature flag

- Check for version in WASM, default to version 1
- Include Circom1 when Circom 2 feature flag is enabled

Currently a lot of code duplication. Once Circom-2 is more stable and
proven to work in the wild, feature flag can be removed.

* Separate Circom 1 and Circom2 witness calculation

* Cleanup

* WitnessCalculator helpers for Circom 1 and 2

Also make helper fn private

* Move comment

* Fix expression return

* cargo fmt

* Add cargo test circom-2 to ci

Improve r1cs_reader for Circom 2 (#13)
* Improve r1cs_reader for Circom 2

Shamelessly taken from https://github.com/poma/zkutil/pull/7/files by @lispc

* Document Seek type restriction

* Doc linter: use automatic links

* Use iter for iterating over sections

* Better error handling with ok_or_else

* Revert "Use iter for iterating over sections"

This reverts commit bc88c726590e250c2e042e9d4b74b77e294e32ec.

Initial Circom 2 support (#10)
* Import circom-2 test vectors

* Add failing test under feature flag

* Add exceptionHandler

* Add showSharedRWMemory

* Add getFieldNumLen32 and disable getFrLen

* Add getVersion

Also print version, n32

* Add getRawPrime

- Disable getPtrRawPrime
- Write as conditional cfg code blocks

* Refactor cfg code blocks

* Add readSharedRWMemory and get prime from WASM mem

- Add fromArray32 convenience function

* WIP: Debug R1CSfile header

field_size in header is 1, not 32 as expected

Don't see anything recently changed here:
https://github.com/iden3/r1csfile/blob/master/src/r1csfile.js (used by snarkjs)

But this seems new: 0149dc0643/constraint_writers/src/r1cs_writer.rs

* Add CircomVersion struct to Wasm

* XXX: Enum test

* Trait version

* Move traits to Circom, CircomBase, Circom2

* Simplify Wasm struct and remove version

* Feature gate Circom1/Circom2 traits

* Use cfg_if for witness calculation

Make normal dependency

* Fix visibilty for both test paths

* Remove println

Can introduce tracing separately

* refactor

* Make clippy happy with imports, unused variables

Early exit in error callback from Wasm (#9)
* Early exit in error callback from Wasm

This avoids Wasm execution hanging due to problems such as wrong public
input.

Mimics circom_runtime behaviour with less detailed debug information.

See https://github.com/iden3/circom_runtime/blob/master/js/witness_calculator.js#L52-L64

Adds test for wrong public input. Without early exit, the test stalls.
With it, the Circom build step fails as expected.

* chore: clean up error handling

* ci: add caching
