This release only targets USB Corecell (no change for SPI connexion type).
The USB-SPI bridge firmware, which runs on the STM32 MCU of the USB Corecell, has
been updated for API clean-up and robustness improvements.

> #### Changes

* MCU: USB-SPI bridge firmware binary v1.0.0.
	* Removed obsolete commands (ORDER_ID__REQ_SPI, ORDER_ID__ACK_SPI)
	* Command index shifted after obsolete commands removal (ORDER_ID__REQ_MULTIPLE_SPI, ORDER_ID__ACK_MULTIPLE_SPI)
	* Command parser sends ORDER_ID__UNKNOW_CMD in case of wrong command size.
	* Code clean-up (typo fixed, comments added...)
	* Implemented Error_Handler() function to reset the MCU in case of fatal error.
	* Fixed a potential roll-over issue in read_write_spi() function.
	* Increased delay tolerance for host feedback on USB transfers.
* HAL: Command interface updated for MCU firmware v1.0.0.
	* Removed obsolete commands from enum order_id_e
	* Shifted commands enum index according to USB-SPI bridge update.
	* Removed decode_ack_spi_access() unused function.
* HAL: Added timing debug information under DEBUG_MCU.
