Update guidance on manual input

[stufraser1]

It is not clear to the user what format the data can be entered in.

The csv template doesn’t match the format of the pre-loaded data which might confuse.

WB request: More explanation on the structure of the data required is needed as not obvious. Maybe show two examples in the template, one for years and one for simulations (and explain any zero entry is assumed no event, not blank).

• Could the template be more partially filled in, with some examples in the template to show how to input cat-model output (i.e., with simulations 1,2,3, not 2001,2002 etc.), making clear that any entries with a zero loss are assumed a no event year and incorporated in the analysis (i.e., bring the average down).
• The user guide should provide examples (WB tested this and people interpreted how to do it differently)
• Add link to this section of guide, in the App.

Propose to add in this section:
"4. Compile for each country and hazard risk, a separate input Excel file:"
of https://github.com/IDF-RMSG/DisasterRiskPooling/blob/gh-pages/docs/_sources/components/index_phase1.rst.txt
where the template and example data is introduced.
