Use an API to get USD - TWD exchange rate

[konnovdev]

Problem

Currently, we are hardcoding USD - TWD conversion, see Body.vue:

      usdConvert(convert) {
        return Number(Math.round(convert * 27.65));
      },

which is not even close to the current exchange rate of 32 TWD per USD.

Solution

I suggest to use some API that has a reasonable free tier for fetching the current exchange rate
