Expected Behavior

Test should pass successfully on all supported Go archs.

Actual Behavior

Unit tests failed to build on 32-bit archs due to untyped int overflows.

$ GOARCH=386 go test ./unit
# github.com/linode/linodego/test/unit [github.com/linode/linodego/test/unit.test]
unit/instance_test.go:92:18: cannot use 30471077120 (untyped int constant) as int value in argument to assert.Equal (overflows)
unit/instance_test.go:93:18: cannot use 22956600198 (untyped int constant) as int value in argument to assert.Equal (overflows)
unit/instance_test.go:94:18: cannot use 53427677318 (untyped int constant) as int value in argument to assert.Equal (overflows)
FAIL    github.com/linode/linodego/test/unit [build failed]
FAIL

Steps to Reproduce

Run tests with a 32-bit GOARCH, e.g. "386".

Note that merely casting the untyped int constants in the unit test to int64 is not a viable solution either, since many of the underlying structs specify members as untyped ints, e.g.

// MonthlyInstanceTransferStats pool stats for a Linode Instance network transfer statistics for a specific month
type MonthlyInstanceTransferStats struct {
    // The amount of inbound public network traffic received by this Linode, in bytes, for a specific year/month.
    BytesIn int `json:"bytes_in"`

    // The amount of outbound public network traffic sent by this Linode, in bytes, for a specific year/month.
    BytesOut int `json:"bytes_out"`

    // The total amount of public network traffic sent and received by this Linode, in bytes, for a specific year/month.
    BytesTotal int `json:"bytes_total"`
}

These are highly likely to overflow when used on 32-bit archs, and really ought to be specified as int64 or even better, uint64. I expect it's not uncommon for instances to transmit or receive more than 2.1 GB in a month.

As it stands, this library really is not suitable for use on 32-bit archs, yet it would have been trivial to make it so.
