Disable OTA for smaller devices, allowing for more customization

[FreezyExp]

Is your feature request related to a problem? Please describe. Trying to add audio libraries to openHASP, the application would no longer fit into the partition size allotted.

Describe the solution you'd like Adding a configuration to disable OTA, switching the 4mb partition scheme to a NO_OTA version that offers more size for the application.

Describe alternatives you've considered I tried alternative audio libraries, both made the application too large to fit.

I could also try to remove some other components, but I would not yet know where to start.

Additional context Placing OTA related code and references in preprocessor statements could further reduce the applications sie.

board_upload.flash_size = 4MB
board_upload.maximum_size = 4194304
board_build.partitions = user_setups/esp32/partitions_4MB_NO_OTA.csv

for your board, extend from this partition profile

Got it building again, thanks fvanroie on Discord for suggesting this.
