WASD: resume the walk right after a weapon set switch (untested in-game)

Switching between weapon classes resets the hero's animation state inside
cUI_Taskbar2::SelectWeaponSet, which dropped the walk for a tick. The hook
sends the WASD walk again at once. Checkpoint before the movement rework.

+Request: the hero stops for a moment when switching weapon sets (F-keys)
+while walking with WASD.

+Measured (state per tick + orders): `cUI_Taskbar2::SelectWeaponSet`
+(`0x6e1440`, ret 8) sends order 0x114 (set, items) and 0x107; between melee
+sets the walk goes on, between a melee and a bow set the hero drops to idle
+for one tick: the weapon class changed, and the switch resets the hero's
+animation state (`0x54e540(1, 0)`). The next WASD tick restarts the walk.
+
+Now: `SelectWeaponSet` is hooked (`skillbar.cpp`) and calls
+`mods::wasd::ResumeWalk`, which sends the walk for the held keys at once.
+Not yet confirmed in-game.
