timestamp bug fix & Fennec parser modification

Fix a bug where the timestamp will not be identified if it doesn't have T. (ex. 2024-09-10 21:41:41 will not be parsed but 2024-09-10T21:41:41 will be parsed correctly). This will result in adding the default timestamp (i.e 1700-01-01T00:00:00) https://github.com/DFIRKuiper/Kuiper/blob/37c0d6fca54611cb33a4853f56e9350340d43c26/kuiper/app/controllers/parser_management.py#L650-L667
Added additional Fennec parsers and modified some parsers that will not recognize the important fields
