Reopen a FAIhandle that has become stale, e.g. by restarting R or loading a workspace containing a FAIhandle variable.

1	fai_reopen( faifh )

faifh

A FAIhandle to a .fai-indexed FASTA file

Use .Call("FAI_reopen", faifh ) to eliminate the slight overhead of using the R wrapper function.

TRUE if call succeeds, FALSE if it fails.
