Version 2.22.0

Changed

• Extend RelationsMapIndex to work with 64bit IDs. This should not change anything for typical OSM use (where relation IDs fit in 32bit), but help with users adding their own relations.
• Removed deprecated support for regexes from osmium::tags::Filter, use osmium::TagsFilter instead (osmium/tags/regex_filter.hpp removed).
• Remove special cases disabling regex support for old C++ libs.
• Various code cleanups.
