v1.7.0

• Added new command \VerbatimClearBuffer.

• VerbatimBuffer environments with the same buffer name now append to the
  same buffer, regardless of the value of globalbuffer. Previously,
  globalbuffer=false caused any pre-existing buffer to be cleared. Now,
  globalbuffer=false causes anything that is appended to the buffer to be
  removed at the end of the environment, but the entire buffer is not
  cleared.

• \FVExtraUnexpandedReadStarOArgMArgBVArg now checks that the final
  argument it reads is braced (#22).

• Text that immediately follows \VerbatimInsertBuffer is no longer indented
  to start a new paragraph.

• Updated tcblisting usage in docs for compatibility with the latest
  tcolorbox.
