fix: x3d defs caching

[christopher-krause]

If we use this parser for multiple files with identical DEF signatures this caching will remove necessary definitions for the x3d.

Now it will be empty for every new parser.

@christopher-krause I like this change, but wonder if ALL the x3d* control variables should be moved inside the createX3DParser() function. Have you tried that?

[christopher-krause]

@z3dev Not yet, for my purpose it was fine to just move this part.

Now you can take a look, all tests passed in this package. Tests for the project are failing because of some kind of Event issue in @jscad/web.

Hmm... i did a clean install from this branch, and ran all the test suites successfully. All CI builds/tests passed as well.

I think these changes are fine.
