dev "convert" functions still check for sp's "CRS" class instead of sf's "crs" class

[mhpob]

The lower case means that the functions will not recognize the input CRS.

• https://github.com/ocean-tracking-network/glatos/blob/dev/R/util-convert_otn_erddap_to_att.r#L197-L202
  • blue_shark_erddap_att will need to be updated
• https://github.com/ocean-tracking-network/glatos/blob/dev/R/util-convert_otn_to_att.r#L204-L209
  • blue_shark_att will need to be updated

Side note: convert_glatos_to_att hasn't been switched over to sf like the others.

• walleye_att will need to be updated if the desire is to switch this function to sf

@jdpye tried to fix a typo in convert_otn_erddap_att afbcb56 that used the Iowa State CRS (EPSG:3426)
