MCF Browser - TMCF Parsing Error Checking

[clincoln8]

The tmcf+csv parser does not currently check for error cases while parsing. Error checking should be included in this step to give the user a precise location of where/why the parsing error is occurring so they can fix their file accordingly.
The parsing errors table displayed to the user should indicate which line of the TMCF and which row in the CSV file is causing the error.

To do this, ParseTmcf class must check for returned the logged errors. back-end/server-api.js will need to be modified to capture the errors found by ParseTmcf. If capturing these errors causes a change to the structure of App's state parsingErrs, then App.jsx will need to be modified. Finally, ParsingErrsTable.jsx component will need to be modified in order to display the CSV row data.
