feat(execution-engine): change behaviour of fold over streams
Change behaviour of fold over streams to make it more similar to pi-calculus channels/names (for more info see #333).
Closes#333.
BREAKING CHANGE:
The new stream behaviour is not compatible with old one, such as
```
(fold $stream iterator
(seq
(call ...)
(next iterator)))
```
will never end after this change (for more info again see #333).
* Refactor `avm-server` interface mod to new crate (#294)
The new crate name is `avm-interface`.
It allows to build fully native air-trace, including pure WASM build.
* Make fully native air-trace build
Unless `wasm` feature is enabled (default), fully native build is
produced. You may build WASM air-trace binary with
`cargo build --target wasm32-wasi --no-default-features --release -p air-trace`
* Fix tracing output on native air-trace build
Wrong option was used.
1. change names to use kebab naming:
`--call_results` -> `--call-results`
`--prev_data` -> `--prev-data`
2. rename `--runtime` option to `--interpreter`, and the associated env variable to `AIR_INTERPRETER_WASM_PATH`.
3. print trace into to stderr

`air-trace run` subcommand allows to run AquaVM on any data, it allows to define most AquaVM inputs, providing defaults for most of them, and sets up either human-readable or JSON tracing output, the latter can be later processed by `air-trace stats`.
Anomaly data input is also supported, that is useful for slow data investigation.
Native execution mode can be used for native profiling. Please note, however, that current version cannot be built natively on Apple Sillicon processor yet, as invariably depends on the `avm-server` because of leaking types that should be refactored or hidden. The `--repeat` option can repeat the execution several times for the execution to dominate on input data reading and output.
High-level or rare calls have "info" trace level, instructions are "debug", and sub-instruction calls are "tracing". Over-detailed tracing can induce overhead that spoils timing data.
