update .nimble and .lock files to work 
Make dht compile with new new (0.14+) nimble.

Compilation with Nimble <0.14 can't work, as
the many of the libraries on the dependency
tree are not version tagged. As we can't change
that, two paths remain:
1, use nimbus-build-system (i.e. git submodules)
2, use lock files introduced in nimble 0.14+
First was already working, this fixes second

fix imports: remove pkg/ 
pkg/ is specific to how old nimble handles
packages. Nimble 0.14 (with lock file support)
uses pkg2/

Anyway, pkg or pkg2 are not needed, better remove.

changing async logic for nodes (multi) response 
The previous version was based on the assumption that
that the future of waitMessage is triggered in the
event loop before the next message arrives. This seems
to be true with UDP, where a full cycle of the loop
handles only one datagram, but not true with other
transports, such as the in-memory emulation. This
led to the following behavior:
- 1st response arrives, reqId removed, waitMessage called
- 2nd ... last messages arrive, can't find reqId, so dropped
- waitMessage competes, re-adding reqId, but too late

The new version solves this by collecting SPRs explicitly

initialize wait for response before sending request.
This is needed in cases where the response arrives before
moving to the next instruction, such as a directly connected
