feat: Metadata management scanner (#749)

* feat: MWP fast Rust-processed QR scanner frontend

* build: temporarily switch dependency rust-native to side branch

* feat: implement rust code for fountain parsing. Saving point for partial dependencies upgrade attempts

* feat: add metadata through fountain QR codes! (go to network settings>"network name">ManageMetadata>Fast Qr Scanner)

* fix: lint and types

* fix: typo in constants

* fix: multiple minor bugs

* refactor: return rust native libs where they belong (#751)

* ref: return rust native libs where they belong

* docs: lost gitignore

* refactor: move reference animated qr code generator to external repository

* build: move header files in ios build part

* build: add more memory for ios node build

* build: add more memory for ios node build in a different way

* build: revert ios build changes, modify bitrise script to allocate less memory

* build: duplicate headers for ios

* fix: Transaction parser (#754)

* feat: parse generic transaction. Ugly but now works.

* test: increase e2e timeout

* fix: lint

* feat: automatically generate built-in metadata (#755)

* feat: add rust code to automatically fetch and generate built-in metadata constants

* test: add extra paths for linter to ignore

* feat: automatically update constants/networkSpecs.ts with new metadata info

* fix: add blake2 hash to metadata handles; use it as ID if no spec_name or spec_version is available

* fix: blake2 hash in networkSpecs constants

* fix: add hashes for centrifuge and edgeware

* fix: metadata autogeneration lint

* build: update failure_derive to 1.8.0

* build: convenience reminder in build script

* fix: multiple fixes to allow versionless metadata

* test: fix unit tests to recognize versioned metadata
