[Feature request] Tilde-expansion in write.fst

[HughParsonage]

Is it possible to support tilde expansion in read and write.fst? I find that write.fst doesn't support it at all, but read.fst does sporadically. ^{I haven't been able to reproduce an instance of it not working}

library(fst)
stopifnot(dir.exists("~/sandbox"))

z <- as.data.frame(x = 1)
write.fst(z, "~/sandbox/z.fst")

Error in fstStore(path, x, as.integer(compress)) :
There was an error creating the file. Please check for a correct filename.

write.fst(z, file.path(path.expand("~"), "sandbox", "z.fst")) # Works

zz <- read.fst("~/sandbox/z.fst") # Works

Hi @HughParsonage, thanks for the feature request! I will apply normalizePath to the path variable before passing it to the C++ code which should enable the use of ~ in the path.
