Cepton-sdk

- New SDK APIs for more capture replay functionality.
- Some calibration data updated.

- Service release of binary images only. There is no SDK interface change.
- Fixed a timestamp overflow bug where reported timestamp is incorrect.
- Fixed captured pcap file problems.
- Removed capture_replay sample as the improved functionality is supported in SDK directly.

- Service release of binary images only. There is no SDK interface change.
- Key reason for this binary release is some networking stability improvements. Notably fixed a problem where sometimes the SDK is holding up the exit process.

- New architechure supported: ARM64. This is primarily for NVIDIA's Jetson TX/TK systems and DrivePX2.
- Explicit support for multiple sensors with per-sensor transformations.
- Decoupled calibration from SDK so that we don't need to rev SDK for calibration changes.
- New improved CeptonViewer binary is included.

- !NOTE: coordinate system changed! (to conform to popular world coordinates such as ROS, distance is Y and height is Z starting from SDK version 0.4)
- Support GPS timestamps (require external GPS hookup)
- cepton_sdk_initialize allows RETURN_UNMEASURABLE flag to support a full frame.
- listen_frame do not return partial frames anymore.
- data_exporter: support --split option
- Calibration improvements
- Stability and thread safety improvements

- Support Mac OSX starting this version
- Improved support for Linux (esp. Ubuntu 14.04)
- Included pre-built binary of CeptonViewer
- Additional sample for data_exporter to dump points into CSV or binary formats.
- Differentiate between real sensor and a replay of capture.
- Networking change to allow multiple applications to share the same device.
