Remove leftover mentions of ADIOS1

We no longer support it, but some docs and code were still mentioning or specializing for it.
This commit removes all mentions.

 In order to set defaults for these value, two further options control the filename:
 
 * ``--openPMD.ext`` sets the filename extension.
-  Possible extensions include ``bp`` for the ADIOS2 backends (default), ``h5`` for HDF5 and ``sst`` for Streaming via ADIOS2/SST.
-  If the openPMD API has been built with support for the ADIOS1 and ADIOS2 backends, ADIOS2 will take precedence over ADIOS1.
-  This behavior can be overridden by setting the environment variable ``OPENPMD_BP_BACKEND=ADIOS1``.

+  In case your openPMD API supports both ADIOS1 and ADIOS2, make sure that environment variable ``OPENPMD_BP_BACKEND`` is not set to ADIOS1.
 * ``--openPMD.infix`` sets the filename pattern that controls the iteration layout, default is "_06T" for a six-digit number specifying the iteration.
   Leave empty to pick group-based iteration layout.
   Since passing an empty string may be tricky in some workflows, specifying ``--openPMD.infix=NULL`` is also possible.
