This PR targets: #253, #76 and to some extent, maybe #208 It features: * api: readPixel on a HiPS object method taking x, y pixel values on the screen. When no screen coo are given, the one of the center screen is used. * api: HiPS.probe a general method using HiPS.readPixel under the hood. It allow to probe the survey pixel values on a pixel, along a screen line and along a great circle arc on the sky * fix: readPixel could throw an exception if the tile has not been received. If so, now, we return a JS null value * fix: retrieve pixels on fits HiPS bitpix=-32 * feat: a new aladin mode called TOOL_COLOR_PICKER. * tool: showColorPickerControl: when clicking on it, enter the TOOL_COLOR_PICKER mode. The user can move the mouse on a pixel to know its value. With a click, the pixel value is copied to its clipboard * fix: restore samp button to connect to a hub * fix: call redraw when calling gotoRaDec to update instantly the imageCanvas #208 * a new global readCanvas method on the Aladin object that will simply read the final image Canvas. User can give a pixel coo, a line (2 pixel coos), a rect (2 pixel coos for the box)
