Populate or fix sonar_software_name and sonar_model for EK60 and maybe other instruments

(Originally discussed in https://github.com/OSOceanAcoustics/echopype/issues/210#issuecomment-822642399)

For EK60:

• Populate Sonar/sonar_software_name attribute. Right now it's left blank; see convert/set_groups_ek60.py#L170
• Sonar/sonar_model attribute entry is "ER60". It should be EK60. Currently EK60 Sonar/sonar_model is set in convert/set_groups_ek60.py#L168 as self.parser_obj.config_datagram['sounder_name'], so that looks fine, unless the datagram sounder_name is parsed incorrectly.

We haven't examined these closely (AFAIK) for EK80, AZFP or other instruments.

These attributes could be examined in parallel with Sonar/sonar_serial_number, #212

I don't think I'm the right person for this issue, since I'm not well versed with the raw datagrams.

I assigned both you and me, because I need to consult you on the naming choice of attributes that we will need to create to take care of the things that may not be in the convention.

Ah! Thanks for that clarification. I didn't see that.

Note: ER60 is in fact the name of the Simrad software. eg, see https://support.echoview.com/WebHelp/Reference/File_formats/Simrad_data_files.htm

We decided to review the detailed content of variables after v0.6.0 now that we have the disruptive type of changes in for v0.6.0.

sonar_model was already addressed for v0.6.0. See https://github.com/OSOceanAcoustics/echopype/issues/681#issuecomment-1339962902.

In this issue, the only remaining topic is sonar_software_name. It may be more convenient to address that question in #681 and close this issue.
