Refactor validation of instruction groups and sequence generation.

[marenz2569]

Currently we check if a supplied instruction is valid in each compilePayload function.

DoD

• [ ] Create a class for the sequence generation functionality.
• [ ] Do checks as soon as possible. E.g. instruction group proportion is not equal to zero.
• [ ] Check against the selected payload it the settings are allowed. This will also allow us to terminate earlier.
  • [ ] maybe wrapping a payload settings in a validated payload settings after we validate it to a specific payload (e.g. SSE2 or FMA)?
  • [ ] only validated payload settings may be provided into other interfaces.
