* Parameters:
* - desired_length: Length of expanded key material
* Even though the standard allows expansion to up to
* 2**16 Bytes, TLS 1.3 never uses expansion to more than
* 255 Bytes, so we require `desired_length` to be at most
* 255. This allows us to save a few Bytes of code by
* hardcoding the writing of the high bytes.
* - desired_length: Length of expanded key material.
* As the type implies, this must be less than 2**16 bytes.
* - (label, label_len): label + label length, without "tls13 " prefix
* The label length MUST be less than or equal to
* MBEDTLS_SSL_TLS1_3_HKDF_LABEL_MAX_LABEL_LEN.
