[FEATURE] Lint Eclipse `.DATA` files with `NOSIM` keyword

[mferrera]

Eclipse's NOSIM keyword can be inserted into the RUNSPEC section of a .DATA configuration file for linting. This keyword will have Eclipse load the configuration file(s) and associated data but without timestepping through the simulation.

• Show a Lint/Validate button when a .DATA Eclipse configuration file is opened in the editor
• When the button is pressed, run Eclipse with NOSIM inserted into the SCHEDULE section
• Parse Error summary, warnings, and errors out

The Error summary looks like this (may or may not be worth grabbing on its own)

 Error summary
 Comments               1
 Warnings              15
 Problems               0
 Errors                 1

Errors and warnings have a format that is easily parsed from the output, prefaced by @

 @--WARNING  AT TIME        0.0   DAYS    ( 1-JAN-0):
 @           SPURIOUS DATA BEFORE TITLE    KEYWORD
 @           /

These warnings and errors are output in sequence after a keyword is read, e.g.

     2 READING INVALID

 @--  ERROR  AT TIME        0.0   DAYS    ( 1-JAN-0):
 @           UNRECOGNISED KEYWORD INVALID  IN RUNSPEC DATA

It was suggested that OPM Flow catches things Eclipse does not, but the two together may be most complete.

There may be a need for special handling of outliers (i.e. consistently flagged issues that aren't issues)
