Multiple money values by power of currency’s subunit

[martinbean]

Currently, monetary values coming back as floats from Reseller Club API responses are assumed to be GBP- or USD-like, and multiplied by 100 to get the value in pence/cents.

Instead, detect the subunit from the currency and then multiply the amount by that to the power of 10, i.e.

$subunit = $currencies->subunitFor($currency);

$amount = $amount * pow(10, $subunit);

This has been added into the master branch, see commit.

@OAFCROB Representing monetary amounts as a money object has, but it assumes the amount is in a currency with two decimal places so just “dumbly” multiplies the value by 100.

Examples:

ResellerClub/src/Orders/BusinessEmails/Responses/CreateResponse.php

Line 53 in bfc6e61

$amount = $this->sellingamount * 100;

ResellerClub/src/Orders/BusinessEmails/Responses/CreateResponse.php

Line 66 in bfc6e61

$amount = $this->unutilisedsellingamount * 100;

Instead, it should use the currency object to determine how many decimal points the currency actually has (as not all currencies are divided into 100 sub-units) and then multiple the amount by that amount.
