 The current RowRange frame is missing handling for several cases.

 None of the following are currently supported:
 RowRange(start=-2, end=-1)
 ROWS BETWEEN 2 PRECEDING AND 1 PRECEDING
 RowRange(start=1, end=2)
 ROWS BETWEEN 1 FOLLOWING AND 2 FOLLOWING

 It's also missing support for EXCLUDE.
 ROWS BETWEEN 1 PRECEDING AND 1 FOLLOWING EXCLUDE CURRENT ROW
