Add map display features from BotW object map

[Chubby-Bub]

There are some map features under the "Filter" tab on the BotW object map that I think would be useful for this one as well.
That primarily includes:

• Ability to filter which field map areas are displayed (though, this would have to account for which layer's areas are selected, or allow that selection in the filter). The BotW map uses numbers, if possible filtering with region names could also be of use (e.g. regions which are part of "Tabantha Frontier", "Necluda Sea" "Central Hyrule Sky", "Eldin Canyon Depths", etc)

• Displaying the map unit grid (A-1 through J-8): I imagine this would be rather simple, and it would be quite useful.

Other features which are on the BotW map but are less important or relevant, in my opinion:

• Displaying enemy safe areas: It's more niche but might be simple.

• Show Hyrule Castle interior: I'm not sure how this one works or if there's even something similar in TotK. I suppose there are the LargeDungeon map screens but I don't think they work the same way, and also might be more trouble than it's worth.

• Show base map: It seems to just change the resolution of the map...?

• Show region outlines and grid: I didn't even realize what this was at first, it just shows what's on the map before you have the actual geography from the tower. It doesn't seem necessary in my opinion.

This code exists in the botw map and is quite simple and easy to move back in ✅

Ability to filter which field map areas are displayed

I am wondering what the UI for this would look like? The FMA (Field Map Area) are collected in a single file and we would need a mechanism is pick which FMA a user would want. 🤔

Displaying enemy safe areas

Do these exist in the data files? I can add this if the data exists. 🤔

Show base map

Apparently there is an issue with the botw objmap. Turning that off, should turn off the actual map, but it doesn't because it is showing the low-res map beneath. Will need to fix that

Show region outlines and grid

This is useful in conjunction with turning off the Base map for people who are trying to find items without getting the towers. I think Bingo uses this more often.

Show Hyrule Castle interior

This was done by hand for botw (you can see the poorly drawn shapes). It took a long while and I am not motivated to do it again
