Summary: This release adds a couple of fixes for issues found by both @andrew-longmore-tessella and @torbjoernt. In one issue, the variable parsing wasn't working as intended for FES-formatted files for tidal currents. In the other issue, the units were not being handled properly for some ascii-formatted models, which caused issues when trying to convert to default units (e.g. from cm to m). This release also adds some minor features, such as an improved representation of pyTMD.io.model objects when using Jupyter notebooks.
