Can't write ScanAngleRank above 90 degrees

[Jean-Romain]

See also r-lidar/lidR#219. Function check_las_validity could be more tolerant with the specification and allow to write numbers up to 2⁷-1.

• modify is_valid_ScanAngleRank to allow range of [-127, +127]
• create is_compliant_ScanAngleRank to warn about rank out of [-90, +90]

library(rlas)
lazfile <- system.file("extdata", "example.laz", package="rlas")
lasdata <- read.las(lazfile)
header  <- read.lasheader(lazfile)
lasdata$ScanAngleRank[1] <- 91L
f <- tempfile(fileext = ".las")
write.las(f, header, lasdata)
#> Error: Invalid data: ScanAngleRank greater than 90
