add three new progress styles
added int to available types
allowed all numeric types in progress bars
added more spinner styles
updated Documentation Link
expanded demo and added asciicast to readme
fixed additional progress examples
added progress documentation
fixed the name of the parallelogram progress-style
fixed default style not being loaded
set default as fallback in case of invalid style
made main.go act as shown in examples
added more documentation to spinner
not the most elegant solution but it works
combined spinners and progress in the example
obviously the blocks couldn't just work…
