+ relocate and deprecate spatialData/Names

changes in version 1.5.1 (2021-12-15)
+ improved coercion methods from SingleCellExperiment to SpatialExperiment
+ add new methods for image rotation/mirroring
+ add path argument to imgSource()
+ user flexibility whether to provide outs/ directory in read10xVisium()
+ documentation updates in show methods
+ additional documentation updates
+ update title and description in DESCRIPTION

changes in version 1.3.2 (2021-07-27)
+ spatialData moved from colData to int_colData
+ restructuring of vignette and added imgData section

changes in version 1.1.700 (2021-05-05)
+ updating roles in DESCRIPTION file
+ adding GeneExpression biocVie
+ switching LazyData to false
+ fixing return value in show method documentation

changes in version 1.1.6 (2021-02-04)
+ removed additional slots in the SPE class definition 
  (i.e. spatialData and spatialCoordsNames)
+ spatialCoords stored in int_colData() = numeric matrix
+ spatialDataNames stored in int_metadata() 
  = character vector specifying a subset of colData()
+ the SPE show method does not include spatialData in colData;
  instead, spatialData/CoordNames are printed separately
+ the SPE constructor now allows specification of spatialData/Coords/-Names
  where -Names can be a subset of the supplied colData();
  spatialData/Coords are thus optional
+ cbind() now allows duplicated sample_ids, 
  which are made unique with a message
+ consistent usage of "spe" for SpatialExperiment objects across 
  all examples (previously, both ve and se were used as well)
+ fixed cache/path-related error on windows in SpatialImage unit tests
+ added unit-tests of SpatialExperiment class validity
+ imgData field in int_metadata is now required 
  to exist (but can be an empty DFrame)
+ colData<- protects sample_id & spatialDataNames 
  fields; spatialData<- protects colData

changes in version 1.1.5 (2021-31-03)
+ version bump to x.y.z format with .z increment
+ general code-style revision to keep to Bioc guidelines including, e.g.
  + usage of accessors (and not @)
  + keeping to a 80-character limit
  + spaces around logical operators (but not function arguments)
  + in-line { for function definitions, if-else statements etc. 
  + re-ordering of roxygen2 documentation to be consistent across scripts
