@param fn Name of the data file corresponding to the index
@param fnidx Name of the indexed file
@param flags Flags to alter behaviour (see description)
@return The index, or NULL if an error occurred
If @p fnidx is NULL, the index name will be derived from @p fn.
The @p flags parameter can be set to a combination of the following
values:
HTS_IDX_SAVE_REMOTE Save a local copy of any remote indexes
HTS_IDX_SILENT_FAIL Fail silently if the index is not present
The index struct returned by a successful call should be freed
via tbx_destroy() when it is no longer needed.
