Incorrectly drops duplicates of some keywords

[lsowen]

First off, thank you for this package, definitely making my life easier. However, I did notice an issue where a keyword (in my case LocalForward) is dropped if it is specified more than once for a host.

Example input:

Host server
     Hostname server.example.com
     ServerAliveInterval 300
     PubkeyAuthentication yes
     IdentitiesOnly no
     LocalForward 8443 api.internal.example.com:443
     LocalForward 9443 api-02.internal.example.com:443

Example program

from pathlib import Path
import pysshconfig


sshconfig_path = Path('./ssh_config')
with sshconfig_path.open('r') as input_fp:
    sshconfig = pysshconfig.load(input_fp)

with sshconfig_path.open('w') as output_fp:
    pysshconfig.dump(results, output_fp)

Expected that the output be the same as the input. Actual:

Host server
     Hostname server.example.com
     ServerAliveInterval 300
     PubkeyAuthentication yes
     IdentitiesOnly no
     LocalForward 8443 api.internal.example.com:443

I am using version 0.0.2

Thanks for raising this! You're correct, pysshconfig assumes that there will only be one instance of each keyword inside a Host block. That was an oversight on my part. I'll come up with a solution.

Maybe a dict of sets? eg:

{
   "Hostname": set("server.example.com"),
...
}

I don't know if every option allows duplicates? Or maybe just some of them?
