Fix ingredient naming bug and use GHA

Patch changes:

• Fixed #22
• Removed lines that saved API responses to a file (leftover from testing)
• Automatic tests are now run with GHA instead of travis

Updated test packages

I noticed that codecov did not work as is should and it was resolved by updating the test packages.

Recipe db validation

Added a validation step that is performed after fetching the recipes from the db. It checks that all ingredients with the same name have the same amount type, if not, the app will terminate with informative error messages.

No comma in file name

Patch release:

• When using gimme_recipe, comma will no longer be included in the recipe file name
• The number of portions is now included in the recipe string:

 Linscurry med kokosmjölk och lime (4 portions): https://www.ica.se/recept/linscurry-med-kokosmjolk-och-lime-720274/

Gimme recipe!

There's a new command in town: gimme_recipe! Use this command to add recipes from https://www.ica.se/recept/ to your recipe database. Read more about it in the README.

Also, g (short from gram) and ml are now supported amount type names.

Support added for different unit of measures

The following unit of measures are now supported as amount types in recipes:

• Liter
  • dl
  • msk
  • tsk
  • krm
• Gram
  • kg

Example: Both of these are valid and correspond to the same amount:

"Water": {"amount": 8, "amount_type": "dl"}
"Water": {"amount": 0.8, "amount_type": "liter"}

First release!

See README for usage.
