Two-state bank selection from a toggle switch.
```cpp pico

#include <cs_midi.h>
using namespace cs;
BluetoothMIDI_Interface midi;
Bank<2> bank(1);
Bankable::CCValue<2> ccVal {
{bank, BankType::ChangeAddress},
{16, Channel_1},
};
SwitchSelector selector {
bank,

};
int main() {
stdio_init_all();
if (cyw43_arch_init()) return 1;
Control_Surface.begin();
while (true) {
Control_Surface.loop();
uint8_t val = ccVal.getValue();
(void)val;
