Pytezos

Fixed

* Always try to fetch the latest storage in off-chain or on-chain views
* Fixed case with `GET` instruction returning `None` with wrong type (key type instead of value type)

Added

* explicit handling of the 401 to return a more meaningful response [kaellis]

Fixed

* Regression in offline view behavior for storage with bigmaps

Added

* Ability to patch VIEW results when using `interpret()` or `onchain_view()`

Fixed

* Results returned from the callback views are now fully-annotated (based on the callback contract type)

Added

* Changelog 😅
* Support for on-chain views:
- Multiple `view` sections are correctly parsed/unparsed
- in REPL `VIEW` instruction works both with self-recursive calls and on-chain contracts (if shell is attached)
- `ContractInterface` provides a seamless interface to views (works pretty much the same as with off-chain views)
* Partial support for global constants:
- added new operation kind `register_global_constant`
- `ExecutionContext` allows to register constants as well
- `ContractInterface` resolves all the constants using the context upon creation
- Since there is no RPC for retrieving on-chain global constants proper resolving cannot be implemented
- It is not possible to use constants in transaction parameters and origination script with high-level entities
* Minimal support for timelock feature:
- `chest`, `chest_key`, and `CHEST` primitives are supported in parser, but not in the REPL
- There are currenty no way to construct a timelock

Changed

* Hangzhou (PtHangz2) RPC endpoint (`hangzhou` is the default shell now), sandbox image (`v11.0-1`)

Fixed

* `pytezos sandbox` CLI command now works properly and provides almost flextesa-like experience at lesser cost
* Operation branch was calculated incorrectly based on the TTL (before `head~{60-ttl}`, after `head~{120-ttl}`)
