Incorrect type for geoIpLookup prop

[usajjad123]

The type of the geoIpLookup is incorrectly defined in IntTelInput.d.ts

Expected Behavior

It should be defined as a function taking callback as an argument: geoIpLookup?: (callback: (countryCode: string) => void) => void

This can be seen in the documentation and code too:

Current Behavior

It is incorrectly defined as: geoIpLookup?: (countryCode: string) => void

This causes typescript error when providing geoIpLookup:

Possible Solution

Only needed slight change in the type as suggested above

Steps to Reproduce

1. Installed react-intl-tel-input lastest version (8.2.0)
2. Provide the geoIpLookup prop

Code:

<IntlTelInput
        preferredCountries={['ae', 'pk']}
        geoIpLookup={async function (cb) {
          const info = await getIpInfo() // calling the ipinfo.io api
          const countryCode = info && info.country ? info.country : 'pk'
          cb(countryCode)
        }}
        formatOnInit={false}
        format={false}
      />

Environment

• Version: v6.1.0
• Browser: all
