    This structure allows the game to have e.g. one-time only events on a map
    or first enter events or permanent changes to the map or permanent script
    calls.

    This header a combination of a trigger script section and a callback script
    section. I don't know if these 'trigger scripts' are the same as the others
    referenced in the map event header, so this might need to be renamed very
    soon.

    trigger scripts: 
    [[Number1 of pointers] Number1 * [2byte pointer to script][00][00]]

    callback scripts:
    [[Number2 of pointers] Number2 * [hook number][2byte pointer to script]]

    hook byte choices:
        01 - map data has already been loaded to ram, tileset and sprites still missing
            map change (3rd step)
            loading (2nd step)
            map connection (3rd step)
            after battle (1st step)
        02 - map data, tileset and sprites are all loaded
            map change (5th step)
        03 - neither map data not tilesets nor sprites are loaded
            map change (2nd step)
            loading (1st step)
            map connection (2nd step)
        04 - map data and tileset loaded, sprites still missing
            map change (4th step)
            loading (3rd step)

        05 - neither map data not tilesets nor sprites are loaded
            map change (1st step)
            map connection (1st step)

        map change:

        loading:

        map connection:
