Add `or` operator to Rego languages. Available via `rego-extensions`
Cargo feature.
If the evaluated lhs value is not false, null or undefined it is returned.
Otherwise rhs is evaluated and returned.
or operator has least precedence, and is left-associative.

- Disable default features in dependencies
- Use anyhow::Error::msg to map errors. Note: anyhow will itself be removed later.
- lazy_static/spin_no_std used in no_std environments
- ensure_no_std binary is built to target thumbv7m-none-eabi to ensure that
there are no std dependencies. thumbv7m-none-eabi target has no std support.
- The opa-no-std feature enables only those Regorus features that work with no_std.
- Enable tests with no_std
- Update sizes of regorus binary in README.md
- Ensure that regorus example can be built with only std
- Ensure that regorus example can be built with no_std

- `std` feature is enabled by default
- By default enable #![no_std] compilation
- Import std create if `std` feature is enabled or if testing
- Use core, alloc types
- Make it clear where std types are being used
- In no std, use BTreeMap in place of HashMap.
HashMap is not available in no std due to lack of a
secure random number generator
Note: The project does not yet compile without std feature being specified.
But it's really close to being able to do so.

If a rule is written to produce a constant value, then not all iterations of loops
within it need to be executed. Execution can stop via early return once the first iteration
that produces a value has been executed.
This brings forth the question : What if one of the subsequent iterations would have resulted
in an error?
e.g:
x {
[1, "hello"][_] + 1
}
Such errors are not raised; consistent with OPA.

- Do not require backtrace feature
- Starting version 1.0.77, anyhow gathers backtrace is std feature (enabled by default)
is specified even if backtrace feature is not enabled.
Therefore specify default features as false.
- Specify version 1.0.45 since that is the minimul version required to successfully
compile regorus

The feature does not interoperate well with other serde_json features like untagged enums.
Fixes#199

* Ruby binding
* use relative regorus crate in ruby instead of a published version, also cargo fmt
* remove unnecessary Cargo.toml, include the top level Cargo.lock in ruby gem
* ruby bindings continued- add eval_rule, fix _json methods, update README.md
also added rubocop-minitest and rubocop-rake, and added more test coverage
* update README.md to include Ruby bindings
Closes#191
* `arc` feature to make engine usable from multiple threads.
`arc` is turned on by default. When enabled, std::sync::Arc
will be used instead of std::rc::Rc. The former makes regorus
types like Engine, Value, ast nodes etc Send, allowing for
usability from multiple threads.
Arc would add a performance overhead though since the reference
counting will now become atomic.

Implement `import rego.v1`
https://www.openpolicyagent.org/docs/latest/policy-language/#the-regov1-import
- `if` required before rule body
- import rego.v1 automatically imports future.keywords
- handle import shadowing
- data, input cannot be shadowed
- deprecated functions as disallowed
- rules must have assignment or body
- `contains` required for parital set
