Incorrect indentation after reduce_operators process

[spinash]

with source file contain this (for reproducing the problem) :

class test():
    def test():
        s=func()
        (s).test = "test"
        print a
    def test2(b):
        print b

I have this error :

# pyminifier  --outfile /tmp/file.py src/test.py 
Traceback (most recent call last):
  File "/usr/local/bin/pyminifier", line 8, in <module>
    sys.exit(main())
             ^^^^^^

    source = minification.minify(tokens, options)
             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    raise IndentationError(
  File "<tokenize>", line 6
    def test2(b):
IndentationError: unindent does not match any outer indentation level

After reduce_operators function (https://github.com/dzhuang/pyminifier3/blob/main/pyminifier/minification.py#L428)
I've write result into file, and this is the result :

class test():
    def test():
        s=func()
(s).test="test"
        print a
    def test2(b):
        print b

Probably the function reduce_operators remove all space before parenthesis and indentation is not correct after processing

Hi @spinash , as mentioned in readme, this repo is not recommended and thus I will not maintain it, please consider python-minifier instead.
