Hi,

Microbiomeseq installed but problem in loading.

> library(microbiomeSeq)
Error: package or namespace load failed for ‘microbiomeSeq’:
 package slot missing from signature for generic ‘coerce’
and classes Raster, SpatRaster
cannot use with duplicate class names (the package may need to be re-installed)

When reinstalled, got the message

> install_github("umerijaz/microbiomeSeq") 
Skipping install of 'microbiomeSeq' from a github remote, the SHA1 (ffa00906) has not changed since last install.
  Use `force = TRUE` to force installation

Any suggession?
