    Description

      On TIKA-1631, users noted that merely detecting an x-compress file could cause an OOM because we were instantiating the stream as part of detection.
      On COMPRESS-382, lfcnassif noted that something similar happens with LZMA.

      Let's work with the Compress project to:
      1) add a static detect that doesn't instantiate the streams (COMPRESS-385)
      2) allow a parameterizable limit on the amount of allocated space for x-compress (COMPRESS-386) and LZMA (COMPRESS-382)

      Until we have a chance to make these changes in the compress project, let's temporarily copy/paste/update from Compress to fix these within Tika.
