Update ADIOS Package

This PR updates the ADIOS package.

**Changes:**

- add latest stable release `1.10.0`
- add previous versions (hashes)
- add default license header
- add build options (shamelessly taken from HDF5 package)
- add validation for excisting FC (as in HDF5) and make optional
- handle mxml dependency correctly (not required in 1.10.0+)
- add `CFLAGS=-fPIC` to build shared (python) libs in ADIOS' lib
- remove `-DMPICH_IGNORE_CXX_SEEK` since it is normally not required
- remove `MPICC/CXX?FC` since `--with-mpi` just performs well
- add transforms:
  - `zlib`: useful (optional) default
  - `szip`: optional (compile often broken)
- add transports that are not as performant as the `.bp` format:
  - `hdf5`: non-default
  - `netcdf`: non-default, close #1610
