pos_vec: Average line direction
In dkopp3/MMASN: Multi-Scale Morphomettic Analysis of Stream Networks

Calculates average direction of a line used for concluence angle

1	pos_vec(p, maxvert = nrow(p), diagnostics = T)

`p`	an points of an sf LINESTRING
`maxvert`	maximum number of line verticies used to fit regression
`diagnostics`	logical used for plotting

this function uses orthogonal regression to find the average direction of a series of points and returns the position vector.

max vert is the maximum number of verticies to fit average line

in some instances the function will return NAN when line is near verticle. Could fix this by changing the maximum verticies

position vector of a line unless diagnostics = T
