This commit fixes the `Destination buffer is too small` error returned by `mbedtls_cert_write` command when the values of `subject_name` or `issuer_name` parameters exceed 128 characters. I have increased the size of these varaibles from 128 to 256 characters, but I don't know if it's the best way to solve this issue... Fixes #315.
