You have many single data points, separated with long stretches of nulls --- no lines. That's why line_gap_fraction isn't working.
By design, WeeWX drivers don't cache data. See the guidelines <https://www.weewx.com/docs/5.0/custom/drivers/#general-guidelines> for writing drivers. However, you could write a simple service that retains the last value and uses it if a null value is seen. Perhaps up to a maximum time. But, there's nothing like that in WeeWX.
