-ldeflate is missing in Makefile after I executed ./configure

[darkcircle]

As we know, HTSlib source tree is also included during compilation process.
HTSlib source tree also needs to refer libdeflate, but configure does not create Makefile containing LIBS="-ldeflate blabla ..."
(refer Makefile line 243.)

so ... in line 33 to 35 of Makefile.am

## xxx_LDADD is some additional libraries besides $LIBS which could collect
## the libraries added by AC_CHECK_LIB
cellsnp_lite_LDADD = @HTSLIB_LIB@

would better to be modified as below,

## xxx_LDADD is some additional libraries besides $LIBS which could collect
## the libraries added by AC_CHECK_LIB
cellsnp_lite_LDADD = @HTSLIB_LIB@ -ldeflate

so I solved compilation problem by fixing the automake script as above.
How would you think about it?
