Include points that lie on the getClusters bbox edge

[SashaMIT]

Summary

• getClusters stores coordinates as Int32 truncations of encode(), then queried with the untruncated value. The southwest and northeast corners of the box were left out.
• The query bounds are truncated the same way. A point at -124, 43 is still left out. The corners of a unit square still all come back.

Test plan

• New test: southwest -123.245515, 43.9150233333333 and northeast -123.192528333333, 44.0307166666667 are returned, and -124, 43 is not
• npm test 19 passed
