fredapi doesn't work anymore with Python 3.9, uses removed function getchildren

[mj-64]

Using Python 3.9, fredapi does not work any longer because it uses the function getchildren() for xml.etree.Elements. This function is deprecated and has been removed with Python 3.9.

I created a pull request to fix it:

Solution: Just remove all getchildren() calls and change to iteration, e.g in get_series():

for child in root.getchildren(): ...

change to:

for child in root: ...

See https://docs.python.org/3.8/library/xml.etree.elementtree.html and https://docs.python.org/3.9/library/xml.etree.elementtree.html, search for getchildren()
