Error when using index files and `--algo 1`

[salvoc81]

I am assuming this behaviour is expected, so please close this issue if it does classify as an issue.
I am trying to use --target-indexed together with the --algo 1 option and I am getting the following error.

Error: --target-indexed requires --algo 0

I will for now deactivate the possibility to use index files in SonicParanoid for now.

Correct, these two options are not supposed to work together.
