* bump_dependencies.md: add nim-results dependency
* change imports stew/results to results
* switching to Nim 2.0.8
* waku.nimble: reflect the requirement nim 1.6.0 to 2.0.8
Adding --mm:refc as nim 2.0 enables a new garbage collector that we're
not yet ready to support
* adapt waku code to Nim 2.0
* gcsafe adaptations because Nim 2.0 is more strict
* dburl.nim: simpler regex that can support db_urls with . and - in hostname
* dbrul.nim: accepting any non-empty sequence for user and password
* dburl.nim: skipping validation for 'sqlite' db paths
