Sartorius Entris II balance.

Interface spec: https://www.sartorius.hr/media/dypfvdsn/entris-ii-technical-note-en-sartorius.pdf (archived: https://archive.vn/NU6DW)

Serial settings:

9600 baud, 8 data bits, ODD parity, 1 stop bit, no handshake, “rn” terminator.

Commands (SBI control commands, format “<Esc> <char> CR LF”):

<Esc>P     print current weight value
<Esc>T     tare (Zero/Tara command)
<Esc>V     zero (Key ZERO)
<Esc>x1_   query balance model
<Esc>x2_   query serial number
The trailing "_" in x1_/x2_ is a literal underscore. <Esc> is the escape
control byte 0x1B; per the spec it is optional, and CR LF terminates.

Not verified: has NOT been tested against hardware in PyLabRobot. A warning is emitted at setup.
