Optimize Inner PixelTree Alignment

[smcguire-cmu]

When performing inner pixel tree alignments, we can bound the maximum number of aligned pixels, meaning we can make inner alignments more performant by using an array of the maximum length instead of appending to a list.

Adds benchmarks for pixel tree alignment.
