Number is implemented using rust_decimal::Decimal which uses a 96 bit mantissa.
TODO:
a) Support u64, i64 variants
b) Determine desired semantics for floating-point
c) Determine desired big integer length
d) Explore other big int/big float crates

This reduces std::mem::size_of::<Value>() to 16 bytes.
String values are also efficiently copied like Objects, arrays, sets etc.
When multiple function rules are evaluated, ensure that constant argument values
match before running the rule. If actual parameter does not match the constant parameter,
then the rule is skipped.

Run regorus against OPA test suite.
To run full test suite:
cargo test --test opa
To run specific folder (e.g semver):
cargo test --test opa -- semver

This allows holding onto objects, caching results etc easily.
However it does introduce the overhead of ref counting.

1. Numeric indices will be converted to strings for refs beginning with `data`
if there is not valid numeric key
2. Error out if input document already contains value for a ref

`OPA_TESTS_DIR=path/to/testsuite cargo test opa -- --shot-output` to run opa tests.
Failing test cases are saved in target/opa/folder for investigation.

1. Skip recording undefined variables
2. Parse `in` correctly if it is not imported.
3. base64.decode
4. Handle `with` modifier for qualified data and input.

Expressions are scheduled based on dependencies and thusthe gathered
expression values may not be in the same order as in source.
Reorder to match the source.

When evaluating rules, upon error the last pushed scope wasn't being
popped from the stack of scopes. This causes incorrect behavior
when there are multiple definitions for the same rule name.
The fix is to make sure that the scopes are popped manually upon encountering errors.
Once the interpreter logic is locked down, then we need to clean up scope management
using Drop functions so that the cleanup happens even during short circuited return.

This needs to be flushed out to be compatible with https://pkg.go.dev/fmt.
All the features of the go format string don't need to be implemented,
only those that are relevant for Rego.

1. MUSL is no longer the default target. This allows building on Mac and Windows.
2. On Linux, code coverage compiler options are supplied by default.
pre-commit, pre-push
- Coverage is turned on only on Linux
- clippy is run on all platforms
github
- MUSL build is tested to ensure that stand alone executables can be created
