** Recieved Data
All versions of the script send a comma seperated list of post
numbers, =post_nrs= and a board =board=. Modern versions of bantflags
also send a version number, =version=, which decides how the returned
data will be formatted.

Data looks like this:
#+BEGIN_SRC http
  POST https://flags.plum.moe/api/get
  Content-Type: application/x-www-form-urlencoded
  
  post_nrs=12345,12346,14444&board=bant&version=1
#+END_SRC
** Sent Data 
*** GetPosts
Returns an =IEnumerable<IGrouping<int, DataRow>>= of post numbers and
their flags where the post numbers are contained in
=post_nrs=. =board= limits the query to only the board we're currently
on.
*** GetPosts_V1
Minimum script version: 0

Flags are converted from an =IEnumerable<IGrouping<int, DataRow>>= to
a =List<Dictionary<string, string>>= by joining the values in the
=DataRow= by "||", which are then split and converted into an array by
the script.

We're doing a needless conversion at both ends which slows the whole
process down, but it's how extraflags is set up and we need to support
it.

Data looks like this:
#+BEGIN_SRC javascript
  [
      {
          {"post_nr": "123"},
          {"regions": "flag1||flag2||flag3"}
      },
      {
          {"post_nr": "456"},
          {"regions": "flag4||flag3||flag3"}
      }
  ]
#+END_SRC

*** getPosts_V2
Minimum script version: 2

Flags are converted from an =IEnumerable<IGrouping<int, DataRow>>= to
a =Dictionary<int, IEnumerable<string>>= which can then be parsed by
the script without any conversion. This format is the same as returned
from the database query, sans the extra information returned by a
=DataRow=

Data looks like this:
#+BEGIN_SRC javascript
  [
      123: [
          "flag1",
          "flag2",
          "flag3"
      ],
      456: [
          "flag4",
          "flag3",
          "flag3"
      ] 
  ]
#+END_SRC
