  CHANGE HISTORY:

    14 June 2023 -- add tell() to the writers to be able to write copc files
    7 September 2018 -- replaced calls to _strdup with calls to the LASCopyString macro
    17 August 2017 -- switch on "native LAS 1.4 extension". turns off with '-no_native'.
    29 March 2017 -- enable "native LAS 1.4 extension" for LASzip via '-native'
    13 November 2016 -- return early FALSE when set_directory() will not succeed
    5 September 2011 -- support for writing Terrasolid's BIN format
    11 June 2011 -- billion point support: p_count & npoints are 64 bit counters
    8 May 2011 -- DO NOT USE option for variable chunking via chunk()
    9 April 2011 -- added capability to write on-the-fly conversion to ASCII
    24 January 2011 -- introduced LASwriteOpener
    21 January 2011 -- turned into abstract reader to support multiple files
    3 December 2010 -- updated to (somewhat) support LAS format 1.3
    7 September 2008 -- updated to support LAS format 1.2
    21 February 2007 -- created after eating Sarah's veggies with peanutsauce
