## About The Pull Request
This PR adds a mail sorting map helper, which during Late Initialization
will apply a sorting location index to the mail sorting disposals pipe
under them. I have replaced the varedits with all mail sorters with the
appropriate map helpers. I have thoroughly tested this, making sure
packages arrived to every location, where possible.
I have also fixed a few issues with the disposals network:
**Tramstation**
- One of the random maintenance segments had a place with no disposal
pipes. This has been fixed
- A sorter was looking for chapel and library packages, but it actually
meant to look for engineering packages
- There was no dormitory mail sorter, I have added one
**Metastation**
- There was no dormitory mail sorter, I have added one
**Icebox**
- There is no experimentor lab in icebox, but there is an
"experimentation" lab, which is good enough, so I have added it as a
location
**Deltastation**
- There was no dormitory mail sorter, I have added one
- Virology was not connected to the disposals network. However, on every
other map, it has a one way connection. I have hooked it up just like
that, so virology mail will arrive safely, and virology trash will go
into space as usual.
**Kilostation**
- Genetics packages were rerouted to the psychologist office
Unsolved issue on kilostation: there is no experimentor on this station,
and there is no space for a disposals in the circuits lab, so sadly, if
you send a package to this destination, it will come back to the mail
sorting office.
**Future improvements**
The TAGGERLOCATIONS list, which is used to retrieve the labels of the
various tags, is frankly unorganizable, and hard to expand. I have
delayed fixing this for a future PR.
I kinda wish to remove the sortType variable, as it is no longer
necessary to have it around with these helpers, but sadly, this would
ruin downstream maps, so I have no plans for this at the moment.
## Why It's Good For The Game
While mapping, having to constantly compare a comment in flavor_misc.dm
to figure out what to varedit a disposal mail sorter to is rather
annoying. These map helpers, similar to the access helpers, will help
with this issue.
Its also good if mail actually arrives.
