WEEK11-BN: add Binary Ninja lesson for Week 11 (structures + functions)

WEEK11-BN.md/.pdf mirroring WEEK04-BN (two examples): 0x0023_structures and
0x0026_functions, each with a dynamic then static pass. Static swaps the flattened
LED pin immediates (LED1<->LED3) and renames a string; dynamic forges the IR key
live. Notes the RP2350 SVD lives in WEEK04. README links it.

 ### Chapter 35: Structures
 This chapter covers structures as well as an intro to infrared basics as we work a infrared receiver and infrared remote controller as it relates to embedded development on the Pico 2.
