- rename asp library to server
- rename aspd binary to captaind
- rename aspd-rpc crate to server-rpc
- rename aspd-log crate to server-log
- rename asp mentions in code to server
- rename asp mentions iin testing to server
- change asp mentions in README, CI etc to server or captaind as appropriate
- and while I'm at it, change ark-lib folder to lib and ark-testing folder to testing
