English name from OpenStreetMap not used

[Russell Porter]

Instead of only using the name tag, we should at least additionally use the name:en tag to get the English localization. This would be pretty useful in Japan: https://openskimap.org/?obj=8f92803adb9b1d0e7fc61dcdf9a3e6a4ace13768#14.12/36.77738/137.88542/-34.8/2

This code is responsible for name extraction: https://github.com/russellporter/openskidata-processor/blob/master/src/transforms/OSMTransforms.ts
