[tor-commits] [stem/master] Allow plaintext enum value

[atagar@xxxxxxxxxxxxxx]

commit 45b98cac45f3f80f6bb319d898ad12775b30823a
Author: Damian Johnson <atagar@xxxxxxxxxxxxxx>
Date:   Sun Jun 23 14:29:14 2019 -0700

    Allow plaintext enum value
    
    Our CollecTor module used None to specify plaintext but we should accept the
    Compression.PLAINTEXT value as well.
