Parser throws Unexpected token COMMA for comma-separated statements

[C9Bad]

I ran into a parsing issue when transpiling some Pine v5 scripts that use comma-separated statements on a single line, e.g.:

//@version=5
indicator("Comma separator test", overlay=true)

a = high, b = low
plot(a), plot(b)

This currently fails with:

Unexpected token COMMA

Thank you for reporting this, tbh I was not aware that Pine Script accepts this syntax. I'll try to fix it in the next release :)
