v1.0.11

Refactored custom instruction insertion function

- Switched from multiple calls to a single function with hardcoded parameters to a single call to a single function
- Better json error detection by matching instruction names in the json against the static map instead of the opposite
- Less hardcoded values, and so removed redundant static_assert for key presence in map (less error-prone)
- Reduced function macro code footprint for less confusion
