Add naive compaction for Query serializationapi

Can be very efficient with the right input, but probably has
degenerative cases where it increases the size. Worst-case size
increase is one character per ID in the result set, so it shouldn't be
an issue.

String lengths for a large search result that was unstorable before:
serialize: 1991874
json_encode: 756249
cooked: 244

And some with more discontinuity:
serialize: 1772238
json_encode: 674751
cooked: 37950

serialize: 164942
json_encode: 65771
cooked: 25369
