MKR 1400 OTA uploads

[Juraj]

A library issue with ArduinoOTA for MKR1400GSM

or

MKR GSM 1400 - WiFi101 OTA library

Heureka, i found the solution!! After copy bytewise from the modem memory to the SD card the file intergrity was given, vimdiff zero and the update with SDU suceeded!! I will try now to speed up the copy process to SD card and bring all together to a example sketch for a working OTA update for the mkr1400.
