more JSON-LD framed examples for performance testing

[VladimirAlexiev]

In umbreak/jsonld-benchmarks#3 we're looking for collections of realistic framing examples (Turtle or JSON-LD docs, plus frames), for the purpose of performance testing.

I know there are about 93 tests in https://github.com/w3c/json-ld-framing/tree/main/tests/frame, but we're looking for more, and bigger file sizes.

Thanks in advance!
