feat: quick addition of 'cur' and 'short' options

[pz1k]

Allow the usage of

• cur?: 0 | 1;

When the asn flag is enabled you'll receive a currency result by default, you can choose to disable this by supplying &cur=0, please note that &cur=1 will not activate the currency display unless &asn=1 is also supplied.

• short?: 0 | 1;

When the short flag is set to 1 we will compress the result, placing the IP address you're testing in the same array as the results instead of a sub-array under the IP address heading. This can make the API easier to parse in some languages but will lock you into only checking a single address per individual request.

Can you confirm if the addition of type IPAddressInfo breaks existing versions?
