WCPS1.5_Throw server GRPC exception when spatial domains are incompatible

[Bang Pham Huu]

Rasql encode function does not catch the exception when calculate 2 different size matrices.

with csv() function, it will throw exception correctly.

rasql -q 'SELECT csv( c[0,-29:100,81:109] * c[0:4,-29:100,81:109] ) FROM eobstest AS c' --out string

Executing retrieval query...rasdaman error 351: Execution error 351 in line 1, column 33, 
near token *: Spatial domains of the binary induce operands are incompatible.

when encode() function will return error in connection

rasql -q 'SELECT encode( count_cells(c[0,-29:100,81:109] * c[0:4,-29:100,81:109] = 8) , "csv" ) FROM eobstest AS c' --out string
