Introduce a test that demonstrates mutation loss caused by premature
loop termination in tablet_sstable_streamer::stream. The code broke
out of the SSTable iteration when encountering a non-overlapping range,
which skipped subsequent SSTables that should have been partially
contained. This test showcases the problem only.
Example:
Tablet range: [4, 5]
SSTable ranges:
[0,5]
[0, 3] <--- is considered exhausted, and causes skip to next tablet
[2, 5] <--- is missed for range [4, 5]
