[FEATURE] Redundant code in array_initializer (array_parser.py)

[Siddhartha Dhar Choudhury]

Describe the solution you'd like
The array initializer list parsing can be done using expression function but has been implemented again which is redundant. Update array_initializer in array_parser.py to use expression() from sim_parser.py to parse expression instead of repeating the same logic.

Hi there! @frankhart2018
Can I work on this?

[Siddhartha Dhar Choudhury]

Sure @Chasmiccoder. Assigning this to you.

@Chasmiccoder I don't know if it is important, but i_temp we use name idx on others files.

Merged.
