Bump org.openftc:easyopencv from 1.6.2 to 1.7.0

[dependabot]

Bumps org.openftc:easyopencv from 1.6.2 to 1.7.0.

Release notes

Sourced from org.openftc:easyopencv's releases.

v1.7.0

• Adds new NATIVE_VIEW viewport renderer option
  • Attempts to provide a balance between the stability of the SOFTWARE renderer and the speedup seen with the GPU_ACCELERATED renderer
  • Drawing is done on the UI thread using the GPU accelerated main canvas, instead of making another canvas as the GPU_ACCELERATED renderer does
• Uses anti-aliasing when drawing the statistics overlay to make text more readable on low resolution screens
• Adds ability for user pipelines to hook into the Canvas rendering of frames to the live view
  • This is an alternate means besides OpenCV calls to draw annotations from a pipeline
  • Allows drawing annotations at the full screen resolution even if performing image processing at a much lower resolution (e.g. 320x240). This allows e.g. drawing actually legible text on a low res image feed.
  • Because live view rendering happens on a different thread than the image processing, in order to make use of this feature, pipelines must call requestViewportDrawHook(object) during processFrame(), providing any type of context object they may wish which encapsulates the data needed to draw the annotations. Pipelines then also need to override onDrawFrame(...) which can receive that same object back, and perform the annotation drawing there.
  • The image sent to the DriverStation is now rendered using an offsceen canvas to ensure that annotations rendered using the canvas will be visible on the DS as well.
• Adds support for MJPEG streaming for webcams
  • Requires FTC SDK v8.2
  • Uses libjpeg-turbo for JPEG decompression routine
  • Allows for streaming at full frame rate at higher resolutions (e.g. 1280x720) which were previously limited to 10FPS due to bandwidth constraints
  • Improves ability to use multiple cameras simultaneously by reducing bandwidth usage
  • CPU load will be increased due to additional overhead from JPEG decompression
  • Uncompressed streaming is still the default; in order to request MJPEG, use the overloaded startStreaming() method in OpenCvWebcam which takes a StreamFormat argument
• Fixes a deadlock when trying to switch cameras when using OpenCvSwitchableWebcam
• Fixes cases where mutex might not be released in internal camera v2 implementation
• Updates OpenCV-Repackaged transitive dependency to 4.7.0-A
