Pull request description:

  This introduces a consistent notation for RPC arguments in `scantxoutset`, `importmulti`, and `deriveaddresses`, either:
  * `"range" : int` to just specify the end of the range
  * `"range" : [int,int]` to specify both the begin and the end of the range.

  For `scantxoutset`, this is a backward compatible new feature. For the two other RPCs, it's an incompatible change, but neither of them has been in a release so far. Because of that non-released reason, this only makes sense in 0.18, in my opinion.

  I suggest this as an alternative to #15496, which only makes `deriveaddresses` compatible with `importmulti`, but not with the existing `scantxoutset` RPC. I also think `[int,int]` is more convenient than `{"start":int,"stop":int}`.

  I realize this is technically a feature added to `scantxoutset` after the feature freeze. If desired, I'll drop the `scantxoutset` changes.
