Throw on invalid keyword arguments

Running `parseall(SyntaxNode, "abc", ignore_error=true)` should throw because "ignore_error" is not a valid keyword.

```julia
julia> parseall(SyntaxNode, "abc", ignore_error=true)
line:col│ tree │ file_name
1:1 │[toplevel]
1:1 │ abc

julia> parseall(SyntaxNode, "abc +", ignore_error=true)
ERROR: ParseError:
# Error @ line 1:6
abc +
# └ ── premature end of input
