These are two heavily parameterized tests that, together, account for about
60% of runtime in the test suite.
FrameFileTest changes:
1) Cache frame files in a static, rather than building the frame file
for each parameterization of the test.
2) Adjust TestArrayCursorFactory to cache the signature, rather than
re-creating it on each call to getColumnCapabilities.
SuperSorterTest changes:
1) Dramatically reduce the number of tests that run with
"maxRowsPerFrame" = 1. These are particularly slow due to writing so
many small files. Some still run, since it's useful to test edge cases,
but much fewer than before.
2) Reduce the "maxActiveProcessors" axis of the test from [1, 2, 4] to
[1, 3]. The aim is to reduce the number of cases while still getting
good coverage of the feature.
3) Reduce the "maxChannelsPerProcessor" axis of the test from [2, 3, 8]
to [2, 7]. The aim is to reduce the number of cases while still getting
good coverage of the feature.
4) Use in-memory input channels rather than file channels.
5) Defer formatting of assertion failure messages until they are needed.
6) Cache the cursor factory and its signature in a static.
7) Cache sorted test rows (used for verification) in a static.
