🚀 Add bank account transaction integration

[alexanderwassbjer]

Implemented an integration that uses GoCardless api to fetch bank account transactions. Then when you want to add an expense you can either fill it manually or you can pick from your transactions and it will automatically be added as an expense. There is also a function to "multi add" multiple transactions at the same time.
If a transaction already has been added to a group you cant add it once again.
GoCardless page

Other changes:

• Fixed dark/light mode.
• Fixed "total expenses" which didn't excluded deleted expenses.
• Added a clear field button to add expense page.
• Changed to on addExpense function redirect link.
• Added the new feature to start page.
• Added information about the new feature to readme.

I have also added i18n support for this feature in another PR that is based on this PR: #89. If this gets merged I can open a PR with i18n support for this aswell.

this looks good overall with some comments. please lemme know what you think!

tysm for this PR really appreciate it. this is really awesome!

think it's best to merge in v2, test thoroughly and release it with other features! (i'll create a new branch)

[KMKoushik]

so it will work on one specific country alone?

[alexanderwassbjer]

No, it should work world wide. The bank provider picker in the settings page fetch all bank providers. It works with either one country or undefined which then returns all the bank providers.
But because the list can be long in that case, I added the env to have a option to only fetch some.

If you have another approach to this, feel free to tell me.
One way is to have a country picker first and then the providers but it feels a bit weird..

[KMKoushik]

we have default currency option, we can get the country from that currency!

[alexanderwassbjer]

I can't find the default currency? If you mean the currency that is set by the user when they try to add a expense it feels a bit weird to use that because it can change?

[alexanderwassbjer]

So for now, it only works with one country in the package I use. https://github.com/nordigen/nordigen-node/blob/9d535ca9d788115d4e199c749432733be3ea6cdd/lib/api/institutions.js#L23

That can be fixed, either in the package or that we have a country picker first.
But if we think of the user case, will it be necessary to have multiple countries at the same instance?

[alexanderwassbjer]

If we want to stick with the env and use it either with no value to fetch all bank providers or filter it based on the env. I have created a PR on the Nordigen-node package and hoping for a merge so we can use it.

Awesome! Iam happy you liked it.
I will go over it again, check your comments and fix some other stuff.

It would be nice if it was released in v2!

@alexanderwassbjer
Some other improvement ideas:

• Encrypt the cache for the transactions.
• Add multiple bank accounts for different providers.

[KMKoushik]

i'll have to think about this over the weekend!
