DP-222 fluent api

[a-ader]

First ugly generated code example.

Usage example:

const api = usePaxful({
    ....
});

await api.paxfulApi.currency.list({
    locale: "ee"
})

const response = await api.paxfulApi.wallet.listAddresses()
response.data.addresses.map(a => console.log(a.address))

const response = await api.paxfulApi.user.info({
    username: "somebody"
})
response.data.lastSeen

const response = await api.paxfulApi.wallet.balance({cryptoCurrencyCode: "BTC"})
response.data.balance
