* Added mcumgr fs handler for getting file hash/checksum, with support for
IEEE CRC32 and SHA256, the following Kconfig options have been added to
control the addition:
* :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_HASH` to enable the command;
* :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_HASH_CHUNK_SIZE` that sets size
of buffer (stack memory) used for calculation:
* :kconfig:option:`CONFIG_FS_MGMT_CHECKSUM_IEEE_CRC32` enables support for
IEEE CRC32.
* :kconfig:option:`CONFIG_FS_MGMT_HASH_SHA256` enables SHA256 hash support.
