[feaLib] Merged LexerError and ParserError
...
This simplifies the public API to the library. For clients, it does
not matter which exact component was detecting an error. And we will
soon have more components; there would be little point in declaring
CompilerError, TableBuilderError, and so forth.

[feaLib] Move block parsing to a separate method

[feaLib] Remove write() methods
