Petascope - Create downscaled collections for Pyramid should regard to source collection's grid domains min and max bounds

[Bang Pham Huu]

In version 10, rasdaman restricts the subsets can be only within the collection's grid domains.

This causes a problem for creating pyramid in WMS with arbitrarily downscaled levels.

For example, this downscaled collection level 8 is created by downscalled collection level 6. And the subset is used fro scale() is not wihin the level 6's grid domain.

Petascope should adjust it to not go outside the source downscaled collection's grid domains for XY axes.

UPDATE s3_test_no_mount_8 as d SET d[0:1431, 0:1532, 0:0] ASSIGN
SCALE(c[0:1909, 0:2043, 0:0], [0:1431, 0:1532, 0:0]) FROM
s3_test_no_mount_6 as c'. Reason: Execution error 356 in line 1, column
