Involves some adjustments necessary for the code to compile with the version of
Nim compiler (1.2.6) provided by latest status-im/nimbus-build-system and to be
compatible with latest status-im/nim-chronos.
Does not include "transport" code added with respect to asynchronous channels
introduced in https://github.com/status-im/nim-chronos/pull/45. That code will
likely be added to this repo in the future.
Note that at present vendor/nim-chronos points to a GitHub fork of
status-im/nim-chronos as two small changes were needed in
vendor/nim-chronos. See: https://github.com/status-im/nim-chronos/pull/154.
