blobCreateSubBlob

Returns a blob that represents a range of bytes in parent. The new blob is always created with #HB_MEMORY_MODE_READONLY, meaning that it will never modify data in the parent blob. The parent data is not expected to be modified, and will result in undefined behavior if it is.

Makes parent immutable.
