v2

Added:
donchianHighLow(len, bands)
  Donchian Calculation with extra parameters.
Originally, the average of the Donchian channel is obtained by adding the tops with the bottoms and dividing the value by 2.
Here this divisor can be customized, not being limited to 2.
Also, in this version the high is caught from the high and the low from low, rather than close
  Parameters:
    len: Lookback length to use.
    bands: Divisor. Default is 2.
  Returns: Average of the highest price and the lowest price for the specified look-back period.

v3
New parameter for VWAP:
anchor (bool): (bool) The condition that triggers the reset of VWAP calculations.
When true, calculations reset; when false, calculations proceed using the values
accumulated since the previous reset. Optional. The default is equivalent to passing
timeframe.change with "1D" as its argument.

v4
Code refactored to improve performance. The improvement in speed can be as much as 50% or more.

So now, to identify the type of moving average, the getMovingAverage function accepts a number (key) corresponding to each type.

The table of keys is in the comment at the beginning of the source code.

The obvious reason is that the integer data type takes up less memory than the string type.

In addition, the getMovingAverageVolume function was created, which works exactly like getMovingAverage, except that it uses the volume (when applicable).

This reduced the number of IFs, reducing the processing required for each situation.
