Library "fibpoint"
A library for generating Fibonacci retracement levels on a chart, including customizable lines, labels, and filled areas between levels. It provides functionality to plot Fibonacci levels based on given price points and bar indices, with options for custom levels and colors.

getFib(startPoint, endPoint, startIdx, endIdx, fibLevels, fibColors, tsp)
  Calculates Fibonacci retracement levels between two price points and draws corresponding lines and labels on the chart.
  Parameters:
    startPoint (float): The starting price point for the Fibonacci retracement.
    endPoint (float): The ending price point for the Fibonacci retracement.
    startIdx (int): The bar index where the Fibonacci retracement starts.
    endIdx (int): The bar index where the Fibonacci retracement ends.
    fibLevels (array<float>): An optional array of custom Fibonacci levels (default is [0.0, 0.236, 0.382, 0.5, 0.618, 0.786, 1.0, 1.618]).
    fibColors (array<color>): An optional array of colors for each Fibonacci level (default is a predefined color array).
    tsp (int): The transparency level for the fill between Fibonacci levels (default is 90).
  Returns: A tuple containing an array of fibItem objects (each with a line and label) and an array of linefill objects for the filled areas between levels.

fibItem
  A custom type representing a Fibonacci level with its associated line and label.
  Fields:
    line (series line): The line object drawn for the Fibonacci level.
    label (series label): The label object displaying the Fibonacci level value.

Normalized Price Points: Version 2 introduces direction ("up" or "down") and normalizes start (sp) and end (ep) prices using math.min/max, ensuring consistent Fibonacci price calculations without reversing level or color arrays:
