Improve TryReadStream with simplification & fix of Stream Invalid Length cutting off Streams (#838) 
* Improve TryReadStream with simplification & fix of Stream Invalid Length cutting off Streams

- Fix of Stream invalid Length issue causing stream data being cut off: fix https://github.com/UglyToad/PdfPig/issues/809

- Improve Stream Token read performance by:
  -  simplifying TryReadStream(), avoiding use of MemoryStream, with benefice of already existing Memory Span of "inputBytes"
  - removing the unecessary List<>

* Add Stream with Invalid Length unit test

* Use of Memory<> instead of direct Span to avoid byte array allocation .ToArray.
Suggestion from (4153e4a1b4 (r1619509165))
