添加自定义双拼方案
一个声母、韵母可以对应一个或多个按键；一对按键不能直接对应多个拼音（需添加模糊音规则），示例模版：
customspjm:={mmsp:{"0": "1" ; mmsp 双拼标识不可重复，sp结尾 "0" 零声母模式
; "1" 两字母的韵母同全拼，a、o、e为aa、oo、ee，三字母韵母为韵母首字母+韵母对应键
; "2" 韵母首字母+韵母对应键
; "a"-"z" 固定零声母
; 双拼显示中文名
,"1": "某某双拼"
; ----例外音节-----------不需要可省去-----------
; （不完全符合下述声母韵母按键关系的拼音）
,"2":{"xiong": "fs"
, "shang": "hs"}
; --------------------------------------------
; ----模糊音正则规则-----不需要可省去-----------
,"3":[["v'", "[iv]'"] ; v结尾的拼音与i结尾的拼音单向模糊; 双向模糊 ["[iv]'", "[iv]'"]
, ["([jqx])u'", "$1[iu]'"] ; ju、qu、xu与ji、qi、xi单向模糊
, ["uan'", "(e|uan)'"]] ; uan结尾的拼音与e结尾的拼音单向模糊
; --------------------------------------------
; zh、ch、sh按键映射，其他声母修改通过例外音节定义
, "ch" : "i"
, "sh" : "u"
, "zh" : "v"
; 韵母按键映射
, "ai" : "d"
, "an" : "j"
, "ang" : "h"
, "ao" : "c"
, "ei" : "w"
, "en" : "f"
, "eng" : "g"
, "er" : "e"
, "ia" : "x"
, "ian" : "m"
, "iang": "l"
, "iao" : "n"
, "ie" : "p"
, "in" : "b"

, "uan" : "r"
, "uang": "l"
, "ue" : "t"
, "ui" : "v"
