Make feature ordering cooperate with --retain-points-multiplier (#188)
* Make feature ordering cooperate with --retain-points-multiplier * Forgot to check in the actual code changes??? * Sort within each multiplier cluster as well as between clusters * Correct description of behavior in changelog * Drag original feature sequence along in megatiles for post-filter sort * Plumb the preserve-input-order flag through overzoom * Sort in overzoom if requested * Use within-tile input sequence numbers, not global sequence numbers * Documentation * Reverse direction of search to prevent accidental skipping * Add some comments about converting between attribute representations

* `-y` *attribute*: Retain the specified *attribute* in the output features. All attributes that are not named in a `-y` option will be removed.
|

* `-j` *filter*: Filter features using the same expression syntax as in tippecanoe.
|

* `-m`: If a tile was created with the `--retain-points-multiplier` option, thin the tile back down to its normal feature count during overzooming. The first feature from each cluster will be retained, unless `-j` is used to specify a filter, in which case the first matching filter from each cluster will be retained instead.

* `--preserve-input-order`: Restore a set of filtered features to its original input order
