Update render to new design. Add a script that will output the render from openscad and scale/crop with imagemagick.
Remove second L298N from electronics panel design.

Created the placeholder for the contact_printer dev server. This will accept a post from the ESP32 with a report after each run. This data can be used in developing features.

Rename variables from 16mmFilm to Film16mm because IDE is suggesting that variables not begin with numbers.

Changed from dev mode to working mode. Lamp turns on after 24 frames. Will make it configurable.

Code is in test mode for getting approximations of the motor speed with no load, under single strand of film load and with 2 films. Should be possible to create a control loop to maintain a roughly-accurate speed.

Add proof of concept blink script for wiring the lamp to be driven by +5V and the TIP120 controlling 3 LEDs at once.

Motor speed is now calculated (flawed). Tests can be run on various PWM speeds, resolutions and with and without loads to determine the ability for the printer run at maximum speeds.

Update README to better reflect current state of the project and add Acknowledgements section.

Make some sacrifices in the DriveMotor class to make it non-generalizable. Working towards porting timing functions from encoder proof of concept sketch.

Motor behavior is stable. Discarded one of the L298N boards: now we can run the drive motor off one channel and both takeup motors off another. DO NOT USE LESS THAN 2A. Using 1.3A the motor controller board draws too much and shuts it down. Removed the rerences to Picture/Stock and am just using takeup. All progress at Worm.
