This commit adds the --socket option to use hledger-web over an AF_UNIX socket
file.
It allows running multiple instances of hledger-web on the same system without
having to manually choose a port for each instance, which is helpful for running
individual instances for multiple users. In this scenario, the socket path is
predictable, as it can be derived from the username.
It also introduces the following dependencies:
- network
- Used to create the unix domain socket
- unix-compat
- Used to identify if the socket file is still a socket, to reduce the risk
of deleting a file when cleaning up the socket
