Branch flash pr with large eeprom (#177)
* save WIP on flash api + header reorder

* reduce diffs to master

* added support for RP2040 (Raspberry Pi Pico)

* support DPT9.009 (airflow) and DPT9.029 (absolute humidity)

* added support for RP2040 (Raspberry Pi Pico) (#145)

* worked on flash implementation

* worked on flash implementation

* added malloc for _EraseBlockBuffer, fixed some bugs

* fixed memoryread and crash while loading KOs (+debugstuff)

* some fixes and debugs

* align to pagesize

* clean up debug stuff, comments ...

* added support for both Eeprom and Flash (NvMemoryType) plattforms.

* changed memoryReadIndicationP to memoryReadIndication
added stdlib and defines

* fixed std::min

* another try for fixing the min problem

* rolled back linux plattform to eeprom

* comments only, hints for plattforms

* bugfix when calculating memorywrites over multiple blocks by mumpf

* added support for EEPROM-Emulation / RAM-buffered Flash
improvements in RP2040 plattform

* fixed typo in KNX_FLASH_OFFSET

* - writebuffersize clarified (PR discussion)
- changed alignment from flashpagesize to 32bit
- added override modifier (PR discussion)
- changed comment regarding flash/eeprom functions for plattforms to override/implement (PR discussion)

* resolved CodeFactor issue
