Imports a log from a string
Parameters
-----------
log_string
String that contains the XES
parameters
Parameters of the algorithm, including
timestamp_sort -> Specify if we should sort log by timestamp
timestamp_key -> If sort is enabled, then sort the log by using this key
reverse_sort -> Specify in which direction the log should be sorted
index_trace_indexes -> Specify if trace indexes should be added as event attribute for each event
max_no_traces_to_import -> Specify the maximum number of traces to import from the log
(read in order in the XML file)
