Requested resolution cannot be set

[andreflorindo]

For the past few weeks I have been testing this driver with a 30xx_25 scanner model. One problem that I have been constantly facing is setting up the resolution using a parameter in the launch file, which does not seem to work properly. An example of the warning messages is provided below.

[ WARN] [1604686042.329222762]: Requested resolution of 2048 not found as available option.
[ WARN] [1604686042.329242178]: Available resolutions:
[ INFO] [1604686042.329251661]: Selecting first available resolution: 2048 `

When the requested resolution is, for example 2048 (or 1024, 512 and so on), the driver cannot find the resolution and always select the "fist available resolution", which ends up been the highest resolution.
