Add 16MB partition large APPS w/ OTA & SPIFFS

[Kadah]

• 7.25MB APPS partitions w/OTA
• Same SPIFFS partition size as default

I attempted to make the menu option brief but also convey the increased size.

I currently don't have one, but an 8MB flash option would complete the set of standard sizes the ESP-WROOM-32D/U and ESP32-WROVER come in.

Is this a generally useful configuration? I don't think we should clutter up the menus. Are your apps getting to 7.25MB? I made the app partitions on ffat.csv 2MB each. Should this be larger?

[Kadah]

When you start adding Bluetooth support to an already largish apps, 2MB starts looking like a minimum.

7.25MB is definitely overkill. The 7.25 number is nothing magical, just where default table expanded to while growing out to 16MB while keeping SPIFFS the same. SPIFFS could have expanded as well, but I've never needed more than a KB or so and that seems like where the fat option comes in.

(The scaling I did would make more sense on an 8MB module, but those seem to be even less common than the 16MB and only cost about 50 cents less.)

(Ignore the random PR close, Github was only showing the "close and comment button. For some reason it has regularly not shown any of the green buttons this week.)

yeah... why so large apps? why not more FS instead?

Maybe it is possible to add an option to create custom partition sizes.
