[Feature-Request] Live Update of ImageManip Mesh

[chengguizi]

Start with the why:

RVC2's ImageManip is a great node that offers good flexibility on remapping the raw image. Currently we use it instead of StereoDepth node internal rectification logic for two reasons:

1. StereoDepth does not support custom camera model which we use
2. StereoDepth cannot handle images of different sizes

To make the mesh more useful, the ability to update the mesh after pipeline starts is desired? In that case we can dynamically tune the mesh (to adapt to changing calibration)

This is discussed there https://discuss.luxonis.com/d/3506-setwarpmesh-after-pipeline-starts/10

Move to the what:

there should be a inputConfig xlink available and we can send in a new mesh during runtime. with the new mesh, image manip node could update how remap looks dynamically.

Move to the how:

Probably can impose a few limitation for ease of implementation. for example, input and output image size remain fixed

Its on our internal tracker, but would likely be more inline with v3 release
