'amount' field doesn't support comma's when buying via moonpay

[Josey87]

Bug description

The IOS app I use displays a comma in the on-screen keyboard when entering the amount of IOTA you want to order via Moonpay. In my region it is common to use a comma as decimal separator (netherlands). The mask in the amount field can't cope with this input, since it gives NaN for several fields that use this number as input. See screenshot.

Bug description

A general description of the bug.

Environment Specs

Apple Iphone 8
OS version 13.2
Trinity version: 1.2.0 (95)

Steps To Reproduce

1. Open trinity, it opens in the balance screen
2. tap "buy IOTA"
3. Confirm the trinity account you want to use
   This opens up the screen where you can input the amount of currency you would like to purchase. My keyboard shows a comma (see screenshot). When entering a normal number, the values are updated in realtime. When entering the comma, the fields go to NaN and $0

Expected behaviour

The software should be capable of processing the given value with the buttons that are supplied on the on-screen keyboard.

1. Display only a dot or a comma, if this is possible
2. Convert a comma to a dot in the background
3. Make the calculation so that it accepts both inputs as correct

Actual behaviour

NaN shows when a comma is entered
