<!-- What / Why -->
<!-- Describe the request in detail. What it does and why it's being
changed. -->

This pull request optimizes the Range class in the following ways:

1. Produce fewer intermediate objects when reducing a range's space
characters to single spaces. This seems to improve bench-subset scores
by up to 5%, and bench-satisfies scores to a lesser degree.
2. Optimize Range formatting with explicit for loops instead, avoiding
an intermediate array creation. This seems to improve bench-satisfies
and bench-subset scores by up to 20%.
3. Calculate Range's `.range` string (used by `.format()` and
`.toString()`) lazily. This seems to improve bench-satisfies and
bench-subset scores by up to 9%.

The external interface for the class stays the same, except for the new
internal `.formatted` property used to cache its lazily calculated
string. `Range#range` property is now also read-only.

There is a new test lazy formatting to ensure full test coverage.

The benchmarks bench-satisfies and bench-subset benefit from these
changes, sometimes by up to 40%. Other benchmark results seem to stay
the same. Here are the affected benchmarks before:
