BESAsciiTransmit now works with server functions

I moved basic code and logic from BESDapResponseBuilder
send_dap2_data() into send_basic_ascii(). It's still a little raw, but
all the tests pass and server functions work including functions used
in combination with selection expressions against Sequences.
