TST/PERF: Re-write assert_almost_equal() in cython #4398

Add a testing.pyx cython file, and port assert_almost_equal() from
python to cython.

On my machine this brings a modest gain to the suite of "not slow" tests
(160s -> 140s), but on assert_almost_equal() heavy tests, like
test_expressions.py, it shows a large improvement (14s -> 4s).
TST: Fix edge cases in assert_almost_equal() + tests #4398

Many of the edge cases were related to ordering of the items, but in
some cases there were also issues with type checking.  This fixes both
of those issues and massively expands the testing for this function.
CLN: Make the name of the test file more accurate

Added handling for v3 advanced segment ids which aren't just ints

The old int based advanced segment ids are deprecated. The new segment
ids are alphanumeric. I know from experimentation that their form
includes alphanumeric and alphanumeric+hyphen. Updated code for both
cases.

Consolidated tests and fixed broken references

In consolidating my test file with the preexisting GA test file, I
found a broken dependency to reset_token_store. It looks like it was
renamed to reset_default_token_store so I updated this file to point to
that. Also added tests around formatting of segment ids to the GA query
to this file.

**CLN** Removed debugging code I added.
