[WIP] make netsim run from examples

[Arqu]

Description

Moves our netsim tests to run from an example and only test the lib part of the code, not the full CLI & blobs.

Things left to do:

• rename the example from new to anything that makes more sense netsim runs it under iroh-transfer
• clean up the example code
• add the option to provide either a relay config or pass in at least the relay url as an argument
• continue the CI adjustment and move all invocations of the netsim runner to run from iroh_v2 and integration_v2 sims (we want a less abrupt netsim switchover)
• convert the remaining sims in chuck/netsim/sims to the new format
• after some time flip back the CI invocations to be regular iroh and integration sims which includes doing the same on netsim and removing the old ones
