Local and Parameter Blocks

[goetzrrGit]

Closes #1460
Adding new directives to the SeqN Grammer to support Parameters and Locals blocks.

• New Directives: The addition of @INPUT_PARAMETER_BEGIN/END and @LOCALS_BEGIN/END directives provides more flexibility and structure for defining Local and Parameters.
• Linter Updates: The linter has been updated to support the new grammar rules
• SeqJSON Export and Import: Both the SeqJSON exporter and importer have been enhanced to fully support SeqJSON Local and Parameters spec.
• Autocomplete: The autocomplete feature has been extended to include the new directives, improving developer productivity.

Testing:
You should be able to use the old grammer

@INPUT_PARAMS L00STR {"allowable_values": ["hi"]} TEMP {"type" : "UINT"}

@LOCALS L001UNIT L001ENUM

As well as the new grammar. The new grammar should be collapsable.

@LOCALS_BEGIN
TEMPERATURE INT
SIZE INT "-1...20, 40..."
STORE ENUM STORE_NAME "" "MACY, ROSS, BEST_BUY"
CHARGE
@LOCALS_END

@INPUT_PARAMS_BEGIN
DOOR_ENABLED INT
X_RANGE INT "...10" "-1,0,3,4,5,9"
@INPUT_PARAMS_END

Verify round-tripping works by exporting a seqJson and reimporting it and verify that the Locals and Input_params are correct.

I'd like to fix the linter typo as that was unclear when I was testing, the others are style and just my opinion.

Functionally it works well, my testing focused on folding and seq.json inspection.

I'll note that even when @LOCALS_BEGIN is present, the content assist can suggest an @Locals directive which will lint as an error. This is a minor issue and neither unique nor new, but I'd like to see how we can reduce on completion suggestion set to valid options. This may be impractical since we support custom linting

Thank you for the review. I fixed the issues you listed in the PR.

We can beef up the autocompletion further and should be okay with custom linting as you can modify/override the autocompletion within the adaptation file

Thanks for addressing my feedback, I'm good merging when @duranb and @goetzrrGit are in agreement on the other items

lgtm!
