rclnodejs v0.7.0

Feature Added

• Add Clock/ROSClock class support.
• Add TimeSource class support, which enables you to attach Clocks to it and update them by receiving the topic of builtin_interfaces/msg/Time.

Improvements

• As the maximum safe integer in JavaScript is (2^53 - 1) due to double-precision floating-point format numbers specified in IEEE_754, the int64_t cannot be represented in JavaScript. We are going to use the string format of the integer for Time and Duration when exceeding the limitation, e.g.

let time = new Time(0, '9007199254740992'); // time.nanoseconds equals  '9007199254740992'

let duration = new Duration(0, '9007199254740992'); // duration.nanoseconds equals  '9007199254740992'
