length_1200 = 1 for all rows when buffer >= 800 #7

Kelly sent me an example file and I was able to reproduce the error. Values look normal for 400 m and 700 m buffer, but length_1200 is 1 for all rows with 700 m and 800 m buffers.

add test for larger buffers to GHA

The logic I wrote for when buffers have zero road length vs non zero road length in incorrect, causing all lengths to be 1 when every row has a buffer with non-zero road length.

PR with fix to come...
