* Closes#1965
* Implements the `unroll` pragma to control the unrolling depth on a
per-function basis.
* Implements parsing of the `inline` pragma.

If an import statement to a missing module occurs when parsing in a
project with no dependencies the error message has the following form:
```
The module Foo does not exist.
It should be in /Users/paul/heliax/juvix-2023/tests/negative/NoDependencies/Foo.juvix
or in one of the dependencies:
```
This PR changes this error message to the `or in one of the
dependencies:` line is omitted from the error message when there are no
dependencies in the project.
This commit also adds a negative parse error test for missing module.
Previously we were:
* discarding the types table
* discarding the name ids state
after processing an expression in the REPL.
For example evaluating:
```
let even : _; odd : _; odd zero := false; odd (suc n) := not (even n); even zero := true; even (suc n) := not (odd n) in even 10
```
would loop in the REPL.
We noticed that the `n` in `suc n` was being given type `Type` instead
of `Nat`. This was because the name id given to n was incorrect, the
REPL started using name ids from 0 again.
We fixed this issue by storing information, including the types table
and name ids state in the Artifacts data structure that is returned when
we run the pipeline for the first time. This information is then used
when we call functions to compile / type check REPL expressions.

- Fixes#1723
- It refactors parsing/scoping so that the scoper does not need to read
files or parse any module. Instead, the parser takes care of parsing all
the imported modules transitively.
