feat(data-modeling):create Financial.CurrencyConversion type

[ll-zerr]

Resolves #32

Creates Financial.CurrencyConversion collection type.

Note: Needed to create the year field type as short text to avoid a comma in the value.

Looks good overall, just a few minor things.

@ll-zerr see the commit I just pushed up! I was able to update the name by recreating the content type and copying over the attributes. In general using the Strapi generate API seems more powerful than the admin panel, at least to create the base api / content type which you can then add attributes to via the admin panel. Want to try it out to create the next content type in the existing financial api?

Steps I followed for the rename:

# 1. generate a new content type ("currency-conversion") & api ("financial")
yarn strapi generate

# 2. copy over the attributes from the old schema.json file to the new one

# 3. delete the old one
rm -rf src/api/currency/

# 4. manually update the types
yarn strapi ts:generate-types

@ll-zerr don't love using biginteger for this, as that will increase the database storage requirements.

Maybe it'd make sense to have year as a string with custom regex validation? Something like ^20\d{2}$ would require it to be a year in the 2000s. You could make this more complex with something like ^2019|202[0-9]$ to allow it to be "2019" or a year in the "2020s".

Ack @ll-zerr so sorry! I didn't realize I hadn't submitted this review two weeks ago when I made it 🙈

[ll-zerr]

@jtfairbank, I made the changes suggested and modified the regex to include a year in the "2030s" to allow for a larger year span past five years.
