Bug in examples/chain_counter.cpp

[smr547]

Call to the DigitalInputChange constructor (line 97) passes delay_time instead of interrupt_type as third parameter. Compiler silently casts the parameter but the button will not work.

API comments

Regarding DigitalInputChange:

• interrupt_type seems redundant given the Class semantics implies only a CHANGE interrupt is applicable
• Likewise config_path is unnecessary as there are no configurable parameters

I'm new to SensESP so my comments may be off the mark. Thank you for an outstanding project.
