Add support for cycleway:both

[Romwriter]

cycleway:both=* tag should be displayed like cycleway=* tag

Suggestion for patching resources/styles/standard/elemstyles.mapcss is:

@990
 way[oneway=no][cycleway=lane]::core_cycleway,
-way[!oneway][cycleway=lane]::core_cycleway {
+way[!oneway][cycleway=lane]::core_cycleway,
+way[cycleway:both=lane]::core_cycleway {
     set laneLeft;
     set laneRight;
 }

@1017
 way[oneway=no][cycleway=shared_lane]::core_cycleway,
-way[!oneway][cycleway=shared_lane]::core_cycleway {
+way[!oneway][cycleway=shared_lane]::core_cycleway,
+way[cycleway:both=shared_lane]::core_cycleway {
     set shared_laneLeft;
     set shared_laneRight;
 }

@1048
 way[oneway=no][cycleway=track]::core_cycleway,
-way[!oneway][cycleway=track]::core_cycleway {
+way[!oneway][cycleway=track]::core_cycleway,
+way[cycleway:both=track]::core_cycleway {
     set trackLeft;
     set trackRight;
 }

Thought :both is especially needed together with oneway=yes. For cases without oneway, cycleway=* is defined as on both sides and :both does not give more information.

I think this is related to https://josm.openstreetmap.de/ticket/10317

cycleway:both=* has a significant increase in usage due to its implementation in StreetComplete.
Even though it only makes up 6% so far compared to cycleway=*, usage is increasing exponentially. See ​https://taginfo.openstreetmap.org/tags/cycleway%3Aboth=lane#chronology

If the effort is kept within limits, I would very much appreciate such an implementation, so that also the values entered by StreetComplete are immediately visible in JOSM in map style. Thanks a lot!

P.S.: From my point of view it would then also make sense that cycleway:both:lane=exclusive and cycleway:both:lane=advisory are considered accordingly. See: ​https://wiki.openstreetmap.org/wiki/Key:cycleway:lane

+1 It is really confusing that JOSM doesn't render cycleway:both=track. Why wasn't this patch applied?

[taylor.smock]

Good question. I haven't applied it since it was 20+ months old, and I have a tendency to prefer newer patches (more likely to apply cleanly, less likely to have been looked at by other maintainers). Maybe #10317? Except I think the reason #10317 was closed as WONTFIX is no longer relevant (it is now documented on the wiki and the usage numbers went from something like 100 in 2014 to more than 22k today).
