Added warning when channels are defined/used multiple times in different blocks -> sometimes breaks the rewrite

Update the "get_code" fnction for operations ->  when the option 'get_OG' is true -> it remove the added "e:" or "t:" + updated the detection of the duplicates to only consider operations (since calls are renamed anyway)

Add initialise condition for the code -> so it doesn't initialises every time (only one when you do the file)

Updated the rewrite of the calls + added filter to catch when an executor appears twice (throws error)

fixed a small bug + i've started to test if the replaces actaully work -> it's a good way to catch errors -> perhaps add them to the rest of the code

Fixed problem with the remove spaces between \. and the jump lines -> it only worked in the case of a single line

Fixed bug with pipe operators when rewritting (within operations and calls) -> using the modified code instead of the OG

Updated the position of subworkflow calls + changed topological order to order of definition in the code

Updated testting -> all you need to do is add workflows to the test folder with the spec graphs and it writes the tests automatically

Added start most influential conditions + such a weird bug fixed with 'get_above_executors' -> when using a dictionnary -> some weird things stuff happens in memory (try woorkflow 17)
