Library "Fibonacci"
General Fibonacci functions. Get fib numbers, ratios, etc.

fib_precise(f, precision)
  Get the precise Fibonacci ratio, to the specified number of decimal places
  Parameters:
    f: Fibonacci ratio (string, in form #.###)
    precision: Number of decimal places (optional int, dft = 16, max = 32)
  Returns: Precise Fibonacci ratio (float)

fib_n(n)
  Calculate the Nth number in the Fibonacci sequence
  Parameters:
    n: Index/number in sequence (int)
  Returns: Fibonacci number (int)

v4
Hard-coded precise fibs for efficiency (rather than deriving them)

Added:
fib_derived(f, precision)
  Get the precise Fibonacci ratio, to the specified number of decimal places
  Parameters:
    f: Fibonacci ratio (string, in form #.###)
    precision: Number of decimal places (optional int, dft = 16, max = 32)
  Returns: Precise Fibonacci ratio (float)
* Deprecated (use fib_precise() instead), but keeping it here for science / experimenting with derivations
