Rework of NewPing v1.8 because of licence issues of NewPing above v1.8

/* HCSR04_herbk library is forked from NewPing v1.8, because NewPing above v1.8 is licenced with limitations to change/extend the code. Autor of HCSR04_herbk library is Herbert Kozuschnik License of HCSR04_herbk library: GNU GPL v3 http://www.gnu.org/licenses/gpl.html

FEATURES:

  • Works with many different ultrasonic sensors: SR04, SRF05, SRF06, DYP-ME007, URM37 & Parallax PING))).
  • Compatible with the entire Arduino line-up (and clones), Teensy family (including $19 96Mhz 32 bit Teensy 3.2) and non-AVR microcontrollers.
  • Interface with all but the SRF06 sensor using only one Arduino pin.
  • Doesn't lag for a full second if no ping/echo is received.
  • Ping sensors consistently and reliably at up to 30 times per second.
  • Built-in digital filter method ping_median() for easy error correction.
  • Uses port registers for a faster pin interface and smaller code size.
  • Allows you to set a maximum distance where pings beyond that distance are read as no ping "clear".
  • Ease of using multiple sensors (example sketch with 4 sensors).

HISTORY: 2023-10-15 Changing output from 0 to MAX_DISTANCE if no obstacle is at range. Changing unsigned int to uint16_t, unsigned long to uint32_t
