No longer use asm-processor (#1824)
* git subrepo pull --force tools/ZAPD

subrepo:
  subdir:   "tools/ZAPD"
  merged:   "b3bfa14cf"
upstream:
  origin:   "https://github.com/zeldaret/ZAPD.git"
  branch:   "master"
  commit:   "b3bfa14cf"
git-subrepo:
  version:  "0.4.6"
  origin:   "https://github.com/ingydotnet/git-subrepo"
  commit:   "110b9eb"

* use CS_FLOAT

* update csdis

* update committed csdata

* finish updating csdis.py

* add script to reextract committed csdata

* dont use asm-processor, use iconv for reencoding utf8 to eucjp

* remove asm-processor csdata usage remnants

* --cs-float hex

* delete tempfile at end of reencode.sh (may want to rm even if compilation fails though?)

* comment reencode.sh

* comment CMD_F

* do not break permuter guessing compile command, by not reencode.sh-wrapping compilation under PERMUTER (thanks anghelo)

* fix the permuter fix

* pad -> sBssDummyNeg1

* reencode.sh: rm tempfile on script exit (including on error)

* renumber sBssDummy vars in zcolchk from 0

* Revert "--cs-float hex"

This reverts commit 85267dc348.

* Revert BSS changes

* Add linemarker to reencoded files for better error message

* fix audio/general.c bss

* make reencode.sh work on macOS

* touch up csdis, csdis_re
