Draft: [split-non-be] ISAR: Dynamic pose offsets for pose correction

• Related issues: #1085 (closed)
• Requested reviewers: @tyagiri, @haeussler

Reason why this change is needed

• This MR enables configuration of the pre-rendering pose offsets via the renderer configuration file, in a session this would ideally be set via backlink from the lightweight device
• This is useful to allow dynamically increasing/decreasing the offsets so that the pose correction does not encounter out-of bounds offsets or perform excessive interpolation

Description of the change

• Pre-rendering pose offsets are now configurable per axis
• This information is now written to the ISAR bitstream but was previously know a-priori at both ends (fixed ROM values)

Affected operating points

• All split rendering operating points
• Output is nonBE due to the nature of the change
• Produced ISAR bitstream is non-BC. Old decoder cannot decode the produced bitstream correctly.
