If the flow_index is not in the literature, I suggest to remove it from this PR and keep it in your project scripts.
Once this PR is merged in, I think it would be interesting to look at additional indices that requires other variables like precipitation, as I think it would provide better physical understanding of processes.
The next step will be to write a test for each index to make sure it behaves as expected. You'll see plenty of examples in the test directory.

Looks good. Please review the changes I just pushed, and add tests for the "indicators" I created.
Note that I added an indexer argument, which lets you pick a season or specific months. Let me know if you believe this is useful or not.
I think the next step would be to have Louise review the finalized PR.

…ean over whole period. This part of the analysis can be done on the user-side. Added support for **indexer, allowing more freedom when selecting the period

This looks good to me.
Here are a few "incoherences" I see, but that may well be expected.
- The high flow is computed with reference fo the median while the low flow is done with reference to the mean. Normal ?
- The high and low flows have their reference computed over the whole period (year) and then the number of days is counted over the temporal subset. The flox index computes both the percentile and the median only over the subset.
…nfusion outweighs the benefits.
