Fix the Ampcor issue that secondary window end pixel out of range in the range direction

[xhuang-jpl]

This PR is to fix the Ampcor issue that secondary window end pixel out of range in the across direction, at window (0, 686), pixel 27632 when the 20+5 data over Chile is processed. The runconfig of the dense_offset is

window_range: 64
window_azimuth: 128
half_search_range: 32
half_search_azimuth: 64
skip_range: 40
skip_azimuth: 75
correlation_surface_oversampling_factor: 16
deramping_method: complex

Following @lijun99's suggestion, we commented out the check of the pixel in image range.
